a netlist is a textfile containing the description of components connection. component id , what is its value or name and the nodes its pins are connected. spice netlist is an input file where user writes them and use it for simulation. also used at the vlsi design where at the end of design phase the netslist is generated from layout an
Hi, how are the wires connected, shows a single green wire connecting to 8 reed switches. this is correct. It is like in your house. One wire coming from the grid goes to several switches in your house. Form the switches there are independet lines to the load(s). Klaus Btw: instead of connecting 8 MUXes to the 64 switc
didn't work on a breadboard at 2Hz, 3, 16, 32, 64, etc., up to 16.7kHz, and changing passive components to fit frequencies, until I connected the NOR gates as inverters See how this compares to an led chaser I experimented with in hardware recently. It has output pulses overlapping, like your diagram. Counter to normal
Could anyone help tell me what type/size components I need with this circuit diagram? 135212135211 I?m going to be using a pump as the motor rated at DC: 3.5-9v 1-3W and my power supply will be DC 8.4V 1.5A. What capacitor, diode, transistor and resistor do I need? Pin 9 will be connected to an Ard
connected how? Through power combiner? Both amplifiers fed by the sample input signal?
resent_n (perhaps a spelling mistake, reset_n?) : This signal, as per standard convention should denote a active LOW reset signal. Means this signal will do a reset of the components connected to it when it is driven to LOW/'0' state. tx_reset : As there is no "_n" here it denotes that the signal affects when it is in HIGH/"1" state. Again it is
Transceiver is a device that can be used for transmit and recieving of data. Thus, two components that do not have a tri-state output can be connected together and commmunicate without contention on a bus. If level translation is required since the two devices work at different power supply voltages, this must be done to prevent device damage. I
Hello, Attached is the circuit which I saw in a paper. Its a power on reset circuit. In the V to I section of the circuit the stability components Rz and Cz are connected between the supply VDD and the drain of pmos transistor PM7. * Why is that so ? * Is it not appropriate to connect them between tha gate of PM7 and drain of PM7 ? Wi
it would be interesting to see the LHS too..then we could see to where the controller FB pin is connected. It looks like a two transistor forward but I expect you knew that. I am looking for the feedback path to the controller but cant see it.
The "L" indentifier suggests that it's rather a common mode choke. The 5-pin IC could be an overvoltage suppressor, just a guess. To which pins of the USB connector are the signals connected?
..... Finally what is the difference between voltage and current source. Both are making current flow through the circuit. ....... In simple terms, in a voltage source, -- its magnitude is constant. --the magnitude of the current flow is determined by the components values connected in the circuit.
What are you wanting to protect? 1) OVP on each supply from line surges? - Then apply TVS or MOV direct to each PS at source with polyfuse in series. 2) OVP on signals on cables from EMI transients to prevent CMOS latchup? e.g. ESD - then apply TVS to signal and signal ground close to cable input. 3) ESD ground shift causing CMOS latchup? W
How to analyse the circuit below when M3 is connected from Vout to Vin ? I'm tempted to suggest you perform an AC and Transient analysis at some online simulator; the circuit is quite simple. Anyway, in adding some components close to M3, I would dare to say that could work as an AGC circuit, just a guess
Your previous posts suggest that you already know something about RF circuits. So I presume you know that RF components are connected by transmission lines, either cable or embedded in a PCB. Here you are asking about single ended ports, connected by coxial lines respectively PCB microstrip and striplines. They have a so-called (...)
I am trying to get s-parameters of simple LC-filter located at the micro-strip substrate while sweeping the length of the central strip. Photo Nr1 shows the circuit: just two ideal L & C components are connected in series with short MLIN and central strip. The length of MLIN is variable (VAR=L). For single values of the length (for example, L =
Use a thermistor (PTC) as temperature sensor and an opamp as comparator (with a potentiometer on the non-inverting input as reference voltage). Once temperature exceeds a value set with the potentiometer, the opamp's output will go low and can switch off a relay that is connected to your lamp. Simple circuit, $2 worth of components.
could I hook it up to my bench power supply and slowly turn up voltage and current to see how it performs You will surely burn the component to see that exceeded some specification, especially if it is not effectively connected to a sink. Semiconductor components as this do not have a body mass that absorbs he
That's probably a shield wire. It should be connected to chassis ground.
Hi, where can I purchase arm cortex (any one m0/m0+/m3..) development in Mumbai(or India)? which could be directly connected to usb something like stm32 discovery boards? Do distributor like arrow or av-net give individual boards or components to a individual? actually i am in a hurry so cannot go on farnell etc
Hi, I build some Momentum components and would like to use them in my ADS schematic simulation. However, I get an error saying that the Momentum component has n-pins, but my schematic has 0-pin. In my schematics, I just set up a S-parameter simulation like how I normally do, with 'terms' connected to the ports of the momentum component. I don
Hi I've designed a single side "dark detector circuit" in Orcad schematics and transfer the circuit to Orcad pcb boards,after arranging the components i tried to make auto rout, and i got a result which is not ok since i found that some tracks crossing each other but in circuit the are not crossed(no connected to each other) and i don't know why a

Hi guys, Im interested in building an LED controlled by an app on my mobile. Im wondering what components would be required in order for this to work. So basically a small battery would be connected to a Bluetooth chip with an RGB on the other side. If anyone has any circuit diagrams that would be great help.
There are dots along the circuit that means you certainly had not connected correctly some components, and this could explain the fluctuating voltage due to some unconnected net. Once it is a simple schematic, I suggest you redraw all of them.
Surely the voltage divider will not treat positive and negative half cycle differently. I rather guess you didn't describe your setup well and have additional components connected to the voltage divider output. If you e.g. connect it to a 0-5 V ADC input, the negative half cycle will be cut because it exceeds the permitted voltage range.
Are you sure it is the drain pin connected to ground and not the source pin? There are often low resistance components between the gate and source but not normally between drian and gate. If you are certain of the connections and the MOSFET itself is OK, look for shorted snubber components and possibly shorted driver circuits. Brian.
IO library comprises of IO cells- which have some additional circuitry like output enable, ESD protection etc.. It has additional components like : IO_Voltage which is the voltage that runs in the rails and is usually higher than the core voltage. The cells have the following :- rail connection (ie. connected to IO voltage/core voltage) leakage pow
Consider the voltage level at the circled node, if that voltage level is calculated by the Kirchhoffs voltage law (summing from the 5V rail to the 0V rail) , but if the node is also connected to the chip, we don't know what components are available inside that chip, can we assume the voltage level not be affected by the components (...)
Because it does not depend on settings, for me the problem is concentrate on the + terminal of the IC'S. Try to shield the components related on the + terminal and filter all the supplies that are connected on that terminal. Consider that any noise on the pin is multiplied by the gain. Mandi
Taking a brief overview at schematic, we can observe that is incomplete due some components are not connected to anything ( JP6, U19, ... ), and others even leaning to misunderstand ( JP11 ). Sounds as a draft resulted from a reverse engineering not yet completed. +++
I did my full adder circuit and created a symbol . Also i did an AND gate and created the symbol. Both the circuits are working correctly when checked separately and i got 1.8v for logic 1 and 24e-9 for logic 0. I created a new schematic with the output of AND gate going to the Apin of the full adder . Now when i simulate , the output of my A
Hi, I have built a PICkit2 clone exactly like the MICROCHIP schematic but with a mix of through holes and SMD components ans without EEPROMs. When I start PICkit2 v2.61, I have a VDD voltage level error but after the hardware is reconized and connected. Then I start the Troubleshoot menu : Step 1 Verify VDD Click on TEST give "Test Pas
I have designed SPI Slave on lattice Mico and connected leds. Can anyone please give me idea how to test that slave alone as I dont have anyother board with me to make it as master and connect it to my slave.Please....I am stuck ...
Most likely you get unwanted ?C resets triggered by relays contact arcing. The actual problem is the insufficient interference immunity of your microcontroller circuit. There are many aspects like ground and power supply wiring, supply bypassing, components connected to the reset input. Adding suitable RC snubbers or varistors across the relay
what kind of trick are you asking for? Just select wire, click at staring point, move your mouse towards end point, click again at end point, and two components will be connected. that's it.
That is quite different. A single bipolar transistor has only PN junctions connected to it's base pin. An IC has lots of other components on the sharing the same silicon and unless designed to do so, a voltage below ground can make the pin draw considerable current and permanently damage it. The extent of damage depends on the type of device and h
Hey everybody, I've been laying out my EAGLE schematic, and everything looks OK. But when I try to layout the PCB, many bypass capacitors show up not connected to the pin they're supposed to bypass, but are instead connected to other things which the voltage supply rail is connected to. For instance, CB3 here, which is obviously (...)
You can believe the datasheet, but can you believe your design? You most certainly need to do some testing to verify that your circuit is working; why wouldn't you? Are you proposing just throwing some components on a PCB and hope that they are all connected properly? You make no mention of your required accuracy and resolution.
Hello! Can you please tell me how these components are connected. Parallel or Series ? 93856 components at points : ed, dc, cf, ef
Here am attaching an application note for charging circuit using that there is a circuit in page 10.I want to know why resistor(Rp) and a Capacitor(Cl) are connected across the level transistor.whats the application of these two components in that circuit?
The most likely reason is something on your board is loading down the signals from the Pickit 2. It probably can't reach the required voltage levels or timing because other components are preventng them being reached. Please keep the wires from the Pickit as short as possible and tell us how you have it connected to the PIC you are programming.
Hi, when moving a wired component in OrCAD PCB Designer 16.0, there are three options for what to do with the etch: (1) do nothing, which leaves the etch alone and just moves the component, (2) Rip up etch, which deletes all etch that was connected to the components, or (3) Stretch etch which turns the etch into a rubber band and gives you weird an
This is the solar panel I will work with (245 Wp): I am in India, and I would like to try to design a micro-inverter that can be grid-connected. This will particularly be useful for the poorer rural communities who would not be able to afford buying inverters from outside the country.
Hi, I wanted to let you know about a research study as I thought some of the people here could benefit from participating. Patexia is offering $3000 in a prior art search contest on circuit pads used in semiconductor packaging to connected to components on an integrated circuit. Given the expertise of this community, I think some of the member h
The only way I see this possible is by using three pin components in isis connected to the pot (each to one pin of the pot), then in ares you can move them individually to any position. You also need to exclude the pot from the PCB (from the component properties), using that way you can use the pot while simulating but it is not shown in pcb. H
How good an EMi filter is depends on ferrite features. The best results offers a bifilar- wound transformer with the coils connected to cancel the EMI components. The gap in ferrite core prevents saturation (at 200 W, the current is high). You can certainly use 2x10 uH coils; filter efficiency depends upon the switcher frequency and harmonics.
The diagram does not reveal how the boards are connected to each other. If they are directly connected so that each board receives input directly from the SMPS, the reason for the drop could be resistance in the PCB tracks. If so, you would need to make them wider. Ensure that there aren't any components in the way, like diodes or transistor (...)
Generally the problem can't be siscussed without knowing how the said port signals are connected inside the components. So dpimref should not have "data" as an inout According to the component definition data of dpimref is a pure output port, connected erroneously to an inout port of ram_sp_ar_aw.
Hai, 12VDC is applied to a tank circuit (L = 100 mH, c= 0.33 micro farad ,connected parallel). What is the maximum current circuit draws from the battery? First time m dealing with the tank circuit pls support me.
