IIR digital filter for delta-sigma decimation, channel selection, and square-root raised-cosine nyquist filtering

A 1.8 V 0.18 /spl mu/m CMOS /spl Delta//spl Sigma/ decimation filter also performs channel-selection and an approximate root-raised-cosine Nyquist pulse-shaping. The 0.1 mm/sup 2/ IIR structure consumes 6.4 mW (26.8 mW) at 64 MHz (240 MHz) oversampling frequency.
