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 ...
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...
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...
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...
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...
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...
For power polygon that primarily carry DC, how critical is it that it is located above a ground plane? Practically not at all. Power planes are overrated. Think about what problem you are really...
Not much. If the wide power trace is good enough to handle the current, then it's, well, good enough. If you really don't have anything else to do with the copper space, then you might as well ma...
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 ...
What you describe is already allowed in Papers. See electrical.codidact.com/help/papers. The papers by Circuit Fantasist are well on topic. Presenting a concept in an accessible way is OK. I ha...
I agree that the particular question was correctly closed. Questions about protocol stacks aren't necessarily off topic. However, this one was because nothing about it had anything to do with ele...
One of the aggrevations Elsewhere were all the vandal and retribution downvotes. They never took the problem seriously. Now it's happening here. Andy was the latest target, twice, recently. I'v...
What happens to the overall accuracy of a resistor if I implement it as multiple resistors in series or parallel? For example, can I get better than 2 kΩ 5% by putting two 1 kΩ 5% resistors in ser...
I recommend using native HTML for lists, and most other formatting for that matter. HTML gets around the ambiguity of what is an item and what is text following the list. The list isn't over unti...
It's not clear what you are really asking, but here is something that might fit your requirements: First, R1 and R2 can be considered separate loads. The transistor therefore switches two loads. ...
I'll assume by "PMIC" you mean a dedicated switching power supply chip. Such a chip contains the PWM generator and receives output voltage feedback at a minimum. They may also include a driver fo...
A switching power supply already is inherently a filter. Current is coming thru an inductor, followed by a capacitor to ground. If you are asking what additional is usually done to filter out chan...
This site isn't appropriate for telling you what to choose. We can, however, give you information on microprocessors versus microcontrollers. Microprocessors and microcontrollers are intended to d...
It seems your question comes down to how to demodulate a SSB (single sideband) signal. Note that the single sideband is already the signal you want, just shifted by some fixed frequency. One way t...
There are various criteria that govern how well power is taken from a nearby changing magnetic field: Distance. The magnetic field diminishes rapidly with distance from the source. Shielding. Pick...
Any deviation from the example antenna could have significant and unintuitive consequences. Unless you have good antenna modeling software and good understanding of antenna physics (which you appa...
A voltage source is "heavily loaded" when something is drawing a large amount of current from it. "Large" in this context is relative to what the voltage source can deliver, or perhaps relative to...
Assuming nothing is broken or wired incorrectly, this is most likely the result of the opamp oscillating wildly. The average may still be about what it should be, so you might not notice with only...
It doesn't quite work that way. You are missing the fact that the current (which the magnetic field is proportional to) decays exponentially. You are also missing the resistance of the coil itsel...
RTOS A RTOS (Real Time Operating System) is much more than a bunch of interrupts. Most true dedicated microcontroller applications don't need any RTOS or any other kind of operating system. Genera...
