Abstract:
An optimized power noise filter for providing a stabilized supply to a multi-chip, multi-module voltage controlled device, said filter comprising:a power supply input line of said controlled device connected through a special low pass filter circuit to a power supply, said special low pass filter circuit comprising a first stage off-chip capacitor and a second stage on-chip capacitor;said first stage off-chip capacitor configured to filter mid-level frequency noises;said second stage on-chip capacitor configured to filter high frequency power noises;at least two on-chip resistors optimized to correct parasitic effects of on-module connections;means for conncting said off-chip capacitor to a chip having said second stage on-chip capacitor in a manner as to maximize filter efficiency so as to also dampen said mid and high frequency power noises.
