Abstract
Described is a novel implementation of a medium and high frequency on-module (off-chip)/on-chip power noise filter for power noise sensitive circuits. To achieve this, a second order low-pass approach is used. The first stage capacitor is located on-module (off-chip), and the second stage capacitor is implemented on-chip.
