vcc filtering
(foldoc) | VCC filtering
A technique for reducing the amount of {Radio
Frequency Interference} spread via power supply connections.
VCC is a common name for the non-ground power supply line
in circuits based on bipolar transistors.
When part of a circuit generates lots of radio-frequency
noise, that portion of the power plane can be isolated from
the rest of the circuit and power delivered to it via a {low
pass filter}, usually a PI filter, as shown in the diagram
below.
source ________inductor_________ load
| |
capacitor capacitor
| |
ground ground
This helps to shield the rest of the circuit from the noise
generated by the load.
