A MOSFET has its gate, source and drain on the top side 1. These structures are sitting on top of the substrate, which is also called body or bulk. The source and drain are n-doped, while the bo...

[I’m asking this question out of curiosity. I understand that this aspect of the CAN bus specification is what it is, and can not change.] The ACK bit in any CAN data frame is dominant. Each rece...

I want to create a schematic symbol and reuse it for multiple ICs which have identical pinouts. For example, OpaMPS, or the venerable SN74LS00, SN74HC00, SN74HCT00. How can I do this in an Altium...

ESD precautions can save a lot of tedious failure analysis. A very inconvenient thing about ESD is that a failure can be attributed to ESD only by ruling out every other possible cause. ESD failu...

A few months ago, I too was looking for answers on how to connect the USB shield with ESD in mind. I always connect the shield through a resistor to ground and a capacitor to ground (100kΩ and 0.0...

[In addition to the answers which have already been posted.] A current sensing circuit like this lends itself to another scheme for ESD protection, which uses only one TVS. Only the line in which...

Is there a mathematical process resembling the terms "digital"/"discrete" and "analog"/"continuous"? Rounding (down, or up, or to the nearest integer) is he mathematical process which discreti...

In this case the antenna connector is the standard horrible little U.FL, which is connected with coaxial to a bigger one grounded to chassis. The main ESD risk is when someone is connecting or re...

I think that the example question in the O.P. should be re-written as design for manufacturing question (DfM, or some other DfX). Electronics market trends questions should be off-topic. It would...

We have to maintain the focus of the Electrical Engineering board at the electrical engineering level. We will be inundated by laymen questions (electronics use, repair, explaining electronics to ...

Thanks for asking. Repair questions are off-topic, in general. We may consider a repair question, if you explain your specific troubleshooting steps, and you understand the design of the device....
