I agree with the answer of Lundin except for point 3 disambiguation. Regarding 3), in case a term does have several different meanings and all meanings are on-topic, then the most common/jangon ...
I propose that we get rid of a lot of bad tags that should never have been created. I went through them all and this is what I think we should get rid of or rename. I'll leave this meta post here ...
What the top part of the circuit really does is drive the counter electrode to whatever it takes to null out the voltage on the reference electrode. The null comes from what the positive input of ...
I am using OPA859-Q1 in one of my applications. It's supply voltage is 3.3V,single supply operation.I am confused about is output swing when operated from 3.3V supply Is the maximum swing is 2.4V ...
why it is acceptable to reduce what appears to be a fairly complex capacitance “network” down to a single value for use in the “allowable capacitance” calculation for a barrier? Because you only c...
Came across this apparent bracket hanging on a communications line. There is one every comm midspan for about a mile. I looked through historical streetviews and they've been there at least since 2...
It was my understanding that the advantage of a pi filter would be the symmetrical nature, where signal direction does not matter. and What would be a reason to decide to use non-symmetrica...
I see that in evaluation design it is mentioned component values will be updated after evaluation, so is it the case that these values are more or less arbitrary and tuned with a VNA during proto t...
The two parts of your question I believe arcing requires high voltage. Then how is arc welding done with about 50 volts? match these two things which must be done, strike the arc, to ...
Understand the physics, and then you don't need these silly and often misleading "guidelines". Such myths may have started with a kernel of truth, but the limitations and conditions under which th...
Hi. I am just getting into PCB design and I consistently see recommendations to never share return paths between signals. It seems this is to avoid noise due to the shared impedance of the return p...
Your question is answered in the very next sentence in the datasheet after the one you quoted: This split-burden resistor configuration ensures that the waveforms fed to the positive and negative...
How does this work - how does it improve THD performance? As with any transformer connected to a live wire, there will be an AC voltage common mode signal transferred by winding capacitance to...
The below image is taken from Analog Devices design note DN1045. what is the use of M1 and M2? What is the use of REF and D1?
I'm not familiar with this device, but it is possible that different variants were made or were possible with the same PCB. Consider the documentation you have as general guidance, not necessarily...
If so, how would that work without a source resistor? Quite well actually. If you look at the 2SK1109 you'll see that it has this characteristic: - I've highlighted the zero voltage bias po...
You are right in that the gain at 80 MHz is clearly not 100. Both the initial marketing points and the graph seem to agree on a gain⋅bandwidth of 45 MHz. There does appear to be a slight kink in ...
I’m trying to understand the biasing of a 2-terminal electret condenser microphone. The inner workings of a 2-terminal electret microphone are always drawn without a resistor at the JFET source. ...
I’ve a linear sensor array (broadside). The array is 10m long and it contains 20 sensors. There’s a limit on the number of wires. I can have a handful of wires running the length of the array, b...
MathJax is enabled in this community, but it is not mentioned in the formatting help. If MathJax guidance is wanted, there is some in the Mathematics Codidact formatting help (at the end). This co...
I am using an IR transceiver in my design.This IC is working at 3.3V supply.This IC need not be on always so I decided to give a control to it's shut down pin (Pin no 5,Shutdown Input. Active low)....
These 9V batteries don't fail like it in normal use, not even when they are very old. They do this only when they are non-rechargeable but are being recharged. There may be a fault in the bed circ...
I was looking for electret condenser microphone preamp topologies. I’d like the preamp to run on a single supply, so I’ll have to introduce an output offset. Saw two topologies for introducing th...
There is no direct way to determine whether the PIC is connected to a CAN bus. Part of the problem is that the PIC never directly connected to the CAN bus anyway. There is a transceiver chip like...
Hi All! I've been looking at how to perform active battery balancing, and I'm currently struggling to understand which type of transistor to use to act as the switch for the "balancing capacitor"....
