Abstract :
An efficient implementation of recursive running sum filters based on switched-capacitor techniques is proposed. In order to improve the frequency selectivity of these cells, two novel sharpening procedures are proposed. The resulting filter blocks are completely stray-insensitive and exhibit very low element sensitivities
