Abstract :
Extensions of conventional multirate switched capacitor (SC) polyphase networks are developed, yielding efficient SC circuits for two-dimensional analog filtering with finite impulse response. The proposed new circuits offer the advantages of systematic design procedures and reduced silicon area for integrated circuit implementation. A simple design example corresponding to a 3 × 3/finite impulse response (FIR) filter is presented
