Abstract :
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.
