I´m not aware about safety standards on ECG equipments, or even if this would suffice, but I presume that grounding the cable shield would reduce the noise.
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.
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.
Can we reduce coupling Capacitance effect in a bus structure by placing two nets adjacently which are driven in opposite directions?
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??
Hi, What do you guys think of using an AC power transformer at the input of a SMPS? I know this idea may sound weird... but it came from the following: We are working in a solution to replace a SMPS that fails very often. Since cost and size are not very important for this design, we thought in put an AC power transformer at SMPS's input.
thank you. i understood that my doubt is we can reduce our clk cycles right using assign statement ?? here i had some 24 bytes of data i had to pad some 3 bytes of zeros to this 24 bytes of data to make it a 27 bytes of data. i can implement this by taking my 27 bytes as (data_new) of wire (or) wire. if i take it as a wire i can use assign statem
the goal of the CTS step is to reduce the skew, so some buffers are needed to drive the clock properly.
You DO NOT want to operate the opamp on two voltages, instead you want it to detect the two voltages at its inputs then switch its output to turn on or turn off the battery charger. Use the opamp in a simple comparator circuit but you must reduce the input voltages with a voltage divider.
Fold wire in half and wind both halves , then cut one end and reverse direction of one pair then join either end for centre tap so both in phase. ( or dot on same side. of both halves) Then they will be matched and in phase. There are special winding methods to reduce interwinding capacitance and raise SRF as well as increase fill factor. On
To reduce confusion regarding the baud rate generator, read this one:
If R2=R3 , I recall it is Av = R2/R1 is the open loop gain. External Closed loop would lower the output impedance and reduce the gain.
Hello All, Please tell me how to reduce the effect of mismatch during the monte carlo simulation for yield analysis. There is a high drop in the open loop gain of my OpAmp. Thanks in advance
VT is what you make it. One conscious choice made in low voltage technologies is to reduce VT (who wants a 1V VT with a 1V supply?) and this leads to more concern about subthreshold leakage and its control. VT is not necessarily simply substrate / well doping. Many low voltage flows offer multiple VTs so that one size does not have to fit all, wh
Hi, i am very new to PD and i am working on this block which seems to have a very tight setup/hold margin. i see that the setup violating path has a lot of hold fix cells put in and if i try to reduce the dly or remove the delay cells, it breaks the hold . if i even try vt swapping or upsizing, the hold breaks. there is no noise in the path. i am
Pipelining is the insertion of registers to increase the latency. The reason we do this is to reduce the amount of logic between registers to improve the overall maximum clock frequency. I not exactly sure of your question. If you set the latency to 9, the output will come out 9 clocks after it is input.
Hi I'm using lm386 audio amplifer with landline circuit.Here i'm facing lot of noise issues.How to reduce noise?

Hello. I have a switch which pulls down (to ground) a pin of a PIC18F65K22 Micro to give a logic low. If the switch is open then the pin is pulled up to the 5V rail via a 47K resistor. Do you think I need a 10n (or thereabouts) capacitor connected to the pin to reduce noise at the pin? When pulled high, and without such a capacitor, do you th
R1 provides thermal stability to the BJT. It helps to reduce the leakage current due to minority carriers at elevated temperatures. Although it can be removed, its good to use it.
