Switched-Capacitor Lowpass Filters Based on Recursive Running Sum Cells
Date of Original Version
An efficient implementation of recursive running sum filters by switched-capacitor techniques is presented. To improve the frequency selectivity of these cells, a novel recursive sharpening procedure is proposed. The resulting building blocks are completely stray-insensitive and exhibit very low element sensitivities. © 1990, The Institution of Electrical Engineers. All rights reserved.
