Clean Power for Every IC, Part 2: Choosing and Using Your Bypass ...
The following plot shows the impedance of a 0.1 µF, 0603 ceramic capacitor with 850 pH of ESL and 50 mΩ of ESR: As discussed in the previous article, a bypass capacitor should provide a low-impedance path that allows high-frequency noise to "pass by" the IC on its way to the circuit''s ground node.
Capacitor for Coupling and Decoupling Applications
A bypass capacitor is placed parallel to a resistor to remove AC noise. A capacitor offers high resistance to low-frequency signals and less resistance to high-frequency signals. As such, low-frequency DC components use the resistor path while high-frequency AC components are shunted to ground through the bypass capacitor.
