Abstract :
Reports a monolithic adaptive filter which has been realized using purely analog sampled-data MOS and CCD techniques. The filter implements a full Widrow least mean-squares algorithm over 65 data points. Central to this design is a novel, compact analog multiplier/accumulator circuit, which is presented in detail. The 65-point adaptive filter, which is cascadable, dissipates 200 mW from a 15 V supply, and operates at sample rates up to 100 kHz.
