See this image which gives four options to place decoupling capacitors: (from http://www.learnemc.com/tutorials/Decoupling/decoupling01.html) I would say option (d) isn't good - I would recommend ...
Recently I'm trying to design a PCB board for an MCU. The problem is I haven't considered any noise aspects before. As I'm in a contest for new electronics product run by our university I have to ...
How important is it to have decoupling capacitors on the same side of the PCB as the IC? I am desperately short of space in a design, and it would really help to put the caps on the bottom side. I ...
This is my first PCB, so please forgive some of my ignorance! I'd like to mount two accelerometers (ADXL193: +/- 250g), orthogonally, on the same PCB, and have a question about noise. The current ...
I'm using 0.01 uF decoupling capacitors in a 0805 package, on each Vcc/GND pair of my CPLDs. So, around eight capacitors in total). I find it a bit easier to route the board if the decoupling ...
We have designed quite a few FPGA-based boards, and so far, we have used a lot of bypass capacitors. Our rule of thumb was, "as many as we can". In our next design, we would like to reduce the part ...
I guess I've been somewhat ignorant when it comes to the finer details of pcb layout. Lately I've read a couple of books that try their best to lead me on the straight and narrow. Here is a couple of ...
