Abstract :
The existence of a class of switched-capacitor (SC) finite-impulse-response (FIR) filters that can be used to decimate a delta-sigma modulator (DSM) output without decreasing the signal-to-noise ratio (SNR) in the baseband is shown. The filters have the property that all of their coefficients are integers and symmetric, which makes them especially suitable for MOS switched-capacitor implementation
