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. (1998-01-26)
