Bypass capacitor selection for <100MHz PCBs
Place a decoupling capacitor near every power supply pin of each digital IC, if at all possible.
Typically, this should be 0.1 uF or higher ceramic multi-layer chip capacitor (MLCC), in the smallest …

3-terminal capacitors as bypass capacitor
instead of several bypass capacitors one cold use single 3-terminal capacitor.
In fact, Murata recommends them for exactly that application:
However you might find that, due to using more vias …

Three-terminal linear regulator output capacitor selection
It depends entirely which linear regulator you are using. The datasheet for a good one should tell you specifically what output capacitor is required or if that regulator will be stable without one. I …

Bypass capacitor before or after circuit, does it matter?
It makes no difference.
What matters is (mainly) the loop area from the positive terminal on the IC, through the IC to its ground pin, through copper to the negative terminal of the capacitor, throug …

How do I calculate impedance of a (bypass) capacitor (for simulation)?
function [ Z ] = calcCapImp( f,R, L,C )
Z=sqrt(R^2+(2*pi*f*L-1./(2*pi*C*f)).^2);
end
This is calculating the magnitude of Z, not Z itself.
Z(i)=(Z1*Z2)/(Z1+Z2);%Total impedance is parallel com …

AC and DC signals
Yes. Whenever two circuit elements are connected in parallel, the potential difference across them will be the same.
how? AC signal will pass through capacitor while dc signal through resistor...w …

Is it bad practice to place a bypass capacitor under its respective component?
In many cases its the only practical way to design the board.
For example with a large BGA package the opposite side of the board is the closest place to put a capacitor to most of the possible power …

Why does the capacitor need to be small in RC filter circuits?
Basically, lower valued capacitors can use dielectric materials that have better performance. Less variability due to temperature and bias voltage. Less variability over time. Higher working voltage r …
