Abstract
Describes a 4-tap transposed FIR filter with a modified structure that uses a combination of 2b and 3b capacitor arrays to implement nearly 5b programmability in each coefficient. It is fully-differential, occupies an active area of 11.8mm/sup 2/ in a 2-/spl mu/m CMOS technology, and dissipates a power of 45mW, about a factor of four less than a comparable direct-form FIR filter.
