If the data sheet doesn't indicate that the two devices are matched then sorry, they probably are not and, you should use a matched device like the PMP5201Y that you linked. That data sheet mention...
Your title question about the "Gaussianity" brings up a lot of thorny issues, since noise in electronic components is quite a difficult topic from a physical, fundamental point of view. TL;DR: Fr...
Coming from a background of safety-related applications and industrial control systems, with some maritime applications experience, I could offer a few insights. These kind of game controls are li...
You have mentioned a few points yourself, so I will try to comment on those points and perhaps suggest some reasons to add or not to add a ground plane. You mentioned twisting (I suppose warping) ...
What material is used in the tabs of power packages? (TO-220, D2PAK, etc.) I would assume probably a tin-plated copper alloy, but I can't find a reference. Datasheets don't seem to mention the mat...
I would not do deliberate ground pours on a board like that. It's relatively small, and not exceptionally high frequency. I also wouldn't try to guess what effect or not it might have on the boar...
First, let's redraw your schematic so that it's not so annoying to look at. High voltages go at top, low voltages at bottom, and logical flow left to right: This is not a great soft-start circu...
Like every Product, there is a price-functionality curve, and while it is true that some big ECAD software have capabilities beyond what Eagle or Kicad offer (see other answers), those capabilities...
What are the essential safety features of such types of hardware? One option to make such hardware safer is to make it battery powered. What other safety features are generally recommended? ...
Let's take a soft-start circuit that looks like this: To my understanding, the function can be described as follows: C1 charges to open the gate. Value of C1 will dictate the soft-start delay...
If a data sheet gives the thermal noise (of +3/-3 standard deviations) as 1 uVpp does it mean that out of every thousand samples, 3 will have noise more than ±1 uV at any sample rate? 1000 sps wi...
I have run into an interesting phenomenon related to ceramic capacitors. This question is part of the effort to understand the issue, and eventually work around it. But first, some background of ...
I've accidentally burnt my dimmer with a short. It is a common dimmer with a triac/diac/pot of the simplest configuration (the triac is a BTA16). After replacing the triac, this still does not work...
No, two zener diodes are not equivalent to a DIAC. While they both have a specific breakdown voltage, the DIAC is a special 3-layer device that exhibits a negative resistance characteristic once it...
Certain high voltage resistors are fairly hard to get, such as the HVR37 series from Vishay. I'm looking at redesigning a board that produces 1000V via a transformer, but I want to use parts that ...
I recently realized something blindingly obvious that I'd overlooked for a few years - that I can generate a servicable PWM triangle wave from a micro by using two PWM outputs with timers set to sl...
Which are the parameters I should looking for when picking a flyback diode to be placed across a generic coil, such as a relay? That is: a coil with plain on/off functionality, for example a 24VDC ...
To add to Olin's excellent answer, if you were probing on a digital IO line in order to view a fast changing signal, without the local ground clip (or spring) grounded close to where you make the m...
Regarding scope of embedded systems/firmware When we released Software Development, I made a push to make all forms of embedded systems programming off-topic and re-direct such to this site. The ...
You can't eliminate all noise, use no memory, no processing cycles, and not add some lag. However, you can do much better than a brute force "moving average" filter. FIR versus IIR filters There a...
The days of socketed microcontrollers are long gone. In most cases, the socket would cost more than the micro. Nowadays, microcontrollers, whether in quad flat pack packages or not, are surface mo...
I can't get my CAN bus application (ISO 11898-2, classic "high speed CAN") working and I'm receiving various CAN error frames. These error frames manifest themselves as sequences of 6 bits with my ...
Welcome and thanks, Monica. It might be good to set some basic expectations in terms of schematic diagram rather than word salad, sharp photos in case of identification questions, and inclusion of ...
