Abstract
There is provided a finite impulse response (FIR) filter for filtering an input voltage signal to generate an output current signal, the FIR filter including a plurality of sample and hold (SH) circuits configured to simultaneously receive the input voltage signal, to sample the input voltage signal at successive sample times according to a sample clock, and to generate a plurality of sampled voltage signals, and a plurality of programmable analog multipliers coupled to the plurality of SH circuits and configured to multiply the plurality of sampled voltage signals by a plurality of binary multiplication factors to generate the output current signal.
