摘要

A novel complex-pole switched-capacitor lowpass filter topology is presented. The proposed scheme features sharper roll-off in the frequency response and reduced in-band loss compared with a real-pole filter. It provides higher stop-band rejection for the same bandwidth. Hence, the required filter order and chip area are reduced. These improvements are achieved without adding more active blocks to...
