You can pipeline long combinational paths i.e. add registers at suitable points to reduce the combinational delay. This will improve your slack results...
Not offset per se. But if you operate a dead-balanced front end away from null (like for example, putting a Vdiff=0 input to a Vio=2mV op amp sample) you will reduce the observed AVOL about Vdiff=0 (it will be better at Vdiff=2mV). This is why op amp ATE setups tend to be closed loop with substantial gain elsewhere, so that the input can be force
Yes, you are right.. You can directly connect 3.3V output of Raspberry Pi to TRIGGER input of HC-SR04. It will detect 3.3V as HIGH LEVEL. But the 5V ECHO output of HC-SR04 should not be directly connected to 3.3V rated Raspberry Pi input.. It may damage it.. So you should use additional voltage dividing resistors to reduce 5V to 3.3V compatible wit
Besides a voltage boost function, you also need a means to reduce the voltage which isn't possible in basic boost topology. Considering the low current requirement, a separate linear regulator stage seems more appropriate than a buck/boost topology. Variable boost converters for low current can be found e.g. in flash/processor programming adapto
I don't know what is the clock selection for ADC you can reduce the ADC clock or do with delays between updates. void loop() { Volts_Reading(); Amps_Reading(); delay(1000); //use what ever makes your update smooth.. }
First check you are not overlooking the obvious. 1) Decoupling cap. next to chip across supply. 2) short leads to reduce inductance of wires try to get < few cm max on all leads 3) for ideal fast rise time waveforms avoid using scope probe with tip and gnd clip, instead use pin and barrel instead. 4) choose small cap to reduce drive current < ma
With stripline or microstrip conductor paths around 20 ps/cm you can design delay lines and select one of 40 lines. However stability of the delay is critically dependant on controlled impedance, layout etc. The delay lines would need to be match terminated to reduce reflections. Alternatively you can search for stock [URL="www.digikey.
Arguably, if you have DC, what is the capacitor there for at all. I suspect what you are refering to is a capacitor across DC supply rails, it would be there to reduce the effects of the inductance and resistance of the wiring which would both cause a voltage drop if a sudden load was applied. In that instance, the capacitor would be fitted to wo
I like .png for its lossless compression and very small file sizes (esp. if you reduce the color depth). The GIMP (Gnu Image Manipulation Program) is a good publicly available full featured graphics editor. I only use it on Linux systems but believe you could find a Windows version. When publishing your image will likely occupy a couple of inche
Actually the Op Amps clip the sine wave from linear feedback in 1&2 In 3, the diodes increase the feedback and thus reduce the gain to soften the limiting and prevent clipping which is preferred.
Hi, I have a design with 2 waveports and 1 lumped RLC surface that simulates a capacitor. I have changed the RLC surface into a lumped port to have a 3x3 Z matrix, this way I can change the values of the lumped capacitor in post processing and reduce the 3x3 matrix down to a 2x2 matrix : V1 = Z11*I1 + Z12*I2 + Z13*I3; V2 = Z21*I1 + Z22*I2
hello it seems this sensor deliver a signal trough a capacitor, and need high impedance entry this simple interface wich use only one transistor could be enough .. a zener to limit positive input and a diode connected to +5V DC supply if overvoltage , input imedance decrease a lot , so reduce voltage at very low value.. Another diode shun
what type of fans are they have a pwminput that you can use to reduce their speed so that the battery will last longer....or alternatively , you may be able to use a buck converter to reduce the voltage to the fane so that they draw less current and go slower, again making the batt last longer
Hi, I build Simple ECG circuit it works well. my problem is that when I disconnect cables from body output display 50Hz Noise with full scale peak to peak voltge 0-5volt. when I touch Metal part of circuit like USB output Noise reduce. so how I can solved my problem that when cable are disconnect output goes to 0volt? any help would be greatly app
i am doing project on mimo antenna using complimentary split ring resonator(cssr) 1) it is operating in 2.45GHz 2) to reduce the size of the antenna iam using cssr 3) ADS is the software used for this design
hi i m designing mixer and using current helpers to reduce current through switches, so when i apply ac signal , from where this ac current should flow i mean all ac current pass through switch or partly current can flow through switch and helpers. Your question is quite confusing. Do you try to DC-bia
What you describe is of course not a synchronous buck converter. The body diode can be expected to show worse performance than a regular rectifier diode, but you should review the transistor specification details. In some cases, a synchronous buck converter can be mode switched to asynchronous operation to reduce losses at low output currents. C
You NEVER EVER make a common-emitter amplifier like that. The base current for one transistor part number has a wide range (the hFE value) so some transistors will be saturated (high hFE) and other transistors will be cutoff (low hFE). Negative feedback is needed to effectively reduce the range of hFE and to reduce the distortion. An emitter resist
You need an encoder to reduce the pin requirement. This encoder is one example of reducing the pin counts. You have to find one that suitable for your design. All the best.
Glass has a permittivity of around 4 , the same as paper and circuit board material. Being a good insulator, it will not affect the conducted field at 1MHz however charges may accumulate on contaminated air or surfaces which may result in a partial discharge in a tiny gap < 300Vpp, so keep it clean. Light weight gasses may also reduce the diele
I disasgree! I see no way you can put the PIC to sleep and wake it up when it detects a shorter distance. It can not detect the distance while asleep. Presumably you pulse the ultrasonic sound and time the echo to find the distance. The only way you can reduce consumption is to send the pulses less frequently and shut down unnecessary peripherals
1) For optimal detection the gap should be less than the sensor width, which means any runout (wobble) must be smaller to avoid collision. 2) heat wont bother the sensor, but will reduce magnet strength but smaller gap will improve sensitivity. All you need is 10mT pp to exceed hysteresis which is slightly more than a fridge magnet 3) circuit
Hi, I have some basic idea on how clock gate works & how it may reduce power consumption. Here is a scenario I am curious with: Says I have a design, and I have a bundle of configuration registers. For operation purpose, I just need to write my configuration registers for once when I power up my IC, and I only read these registers values without
Volatile solvents are slightly acidic to reduce surface tension while it is heating up so it becomes liquidus and spreads out then boils off all the flux before it cools. Look at recommended solder temperature profiles and reduce the air flow to minimum to prevent premature drying the entire process might take a minute. If the board is copp
Electrical heating of a wire is caused by the voltage times the current. To reduce the heat then reduce the voltage, reduce the current or reduce both. A transformer does not get hot when it has no load because it operates from AC, not DC. But your solenoid is simply a piece of wire with DC in it so its inductance does not (...)
It is an input filter to reduce EMC to meet compliance requirements. Normally, you will design the filter after measuring the attenuation required at a certain frequency to meet a specific emission's standard. So after doing a pre compliance measurement with an LISN box, you will know which frequencies need attenuation to meet the standard.
do you have pull up on Tx pin ? you can reduce the value as low as 470 ohms and pull down on Rx pin ? value about 2,2K to transmit signal with low impedance..and reduce problem due to noisy environement.. You can also add CMOS trigger defore RX input.. like 74LS14 (TTL) or CMOS CD4093-B or MC74VHC1GT14 or ...
NO, solder resist is not a conformal coating, use bare board. To reduce the spacing you have to have a conformal coating and inspection procedures etc. Don't forget the devices legs have to be covered as well, in fact any exposed metal must be covered if it is going to be at mains potential.
12V, 150W => more than 10amps! what size of wires do you use for power supply , and especially for ground wich is common for MCU and Motors? Add also big capacitor accross the lipo battery output .. to reduce the noise on the power supply. Add also a 100?H inductor on the input line of LM2576 3,3V... For noisy environment, maybe the use of a
The reason is that there is coupling between the array elements. One element by itself will not behave in the same way when it is affected by its neighbors. You can reduce the coupling by spacing out the elements, or using coupling mitigation techniques such as DGSs or EBGs.
Yeah your feedback compensation needs some tuning. You have a lot of ringing, but the low frequency gain is also too low. Try increasing your zero frequencies while decreasing your pole frequencies (basically reduce your k factor ).
how to reduce heat generated across regulator due to mq6 sensor?
The ground should have a big area to stop series inductance in it down the length of the board. If the ground is big and close to conductors which are carrying high frequencies, the adjacent capacitance to ground will reduce the cross talk to other lines. The downside would be the rise/fall times will be slower. Frank
The term "latching current limiter" sounds erroneous or at least misleading. A latching overcurrent protection will shutdown the power supply if the trip level is exceeded once. A current limiter will keep a maximum current value continuously, a foldback limiter will additionally reduce the current with decreasing output voltage, e.g. to reduce the
The very old 74LS08 is a TLL AND gate. Its output is high when both inputs are 2V or higher. But its maximum allowed output current is only 0.8mA when high and is recommended to be only 0.4mA which will barely light an LED. It needs a resistor in series with the LED to reduce the output high current so that the gate is not destroyed.
can any one give clear picture about how to reduce insertion in delay in CTS.
reduce the number of mesh cells. Start with a low value and use adaptive meshing.
You cannot reduce the coupling Capacitance however, because the coupling capacitance is a function of permitivity, the spacing between traces and the length for which they run in parallel. I am curious... if this is a bus how can you reverse the direction of signals in two adjacent lines ?
A DVM can reduce a resistance measurement to a ratiometric measurement with a reference resistor, and zero offset and thermoelectric errors by switching the current excitation. In so far it also cancels most drift effects. An AC measurement may still bring advantages in a certain resistance range, athough it involves it's own parasitic effects like
Hi Folks, Can any one explain how tap cell is used to prevent latchup effect. I know tap cell is used to connect n and p substrate to Vss and vdd respectively. In google I found one more definition tap cell is reduce resistance between vdd and vss. Thanks in advance, kpsr
Can we reduce coupling Capacitance effect in a bus structure by placing two nets adjacently which are driven by drivers in opposite direction.
An emitter resistor is used for a transistor to provide DC and AC negative feedback to automatically adjust the base-emitter DC bias point and reduce AC gain and distortion. Transistor Q1 already has DC and AC negative feedback through R6 so it doesn't need an emitter resistor. The collector load impedance for Q1 is much higher than the value of R
If you are the led using common emitter , reduce the resister value.. Post your schematic..
For EDM you would be better to have a large (>>100) array of 10 uF 100V electrolytic caps in parallel. This will help reduce inductance . SMD will have a much higher SRF which also is important for ionization ripple frequency but generate more EMI. I recommend 10mF rather than 10uF. The key to smooth EDM is a HV spark to trigger the arc and then
Yes different pad sizes will affect assembly. This device will have to be reflowed, you are not going to wave solder a device of this pitch..... Why do you have to reduce the pad size to join the pads?
Well firstly we would need more information, drawings etc to provide any sort of educated guess or you can go and look at the aavid and bergquist sites as they have lots of information on thermal engineering. Got to agree with the cold one, trying to reduce the heat generation in the first place would be the best option.
To reduce load on battery L1, L2 impedance must be high at the applied load DC current. L1 is 10uH is reduced by L2 in parallel which has no value given. switch rate is not given and understand you cannot solve without knowing/sharing these parameters.
hi, i want to eliminate noise at certain frequency in matlab. anyone can help me??
If you aren't doing a serious design, anything goes, but these days avoiding primary transformers is pretty standard to reduce cost, weight and size then there is a PFC encouraged in many countries. Traditional 2-stage converters have independent control loops for the PFC stage and the step-down stage, allowing each converter output to be regulate
Using assign statements is not a magic method to reduce latency. You could make the exact same thing with an always block. wire in_a; wire in_b; wire output_of_the_day; wire yet_another_output; // unregistered AND gate assign output_of_the_day = a & b; // the exact same boring unregistered AND gate always @(*) begin
