I have a very simple design that I'm now working on the PCB layout for. And at the moment I'm thinking about the issue of decoupling capacitors. The board is very simple and only consists of this: ...
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 ...
