Switched-capacitor realization of FIR filters
N. Reddy, M.M. Swamy · IEEE Transactions on Circuits and Systems · 1984
Finite impulse response (FIR) filters can be realized without multipliers and delays by delta modulating the input signal [5]. In this letter, we describe a stray-insensitive switched-capacitor (SC) implementation of such delta modulation FIR filters.
