A single-chip video ghost canceller

A 450 K-transistor video ghost canceller chip, which implements a flexibly configurable IIR and FIR filter, is described. A very compact digital filter tap operating at a pixel rate of 14.32 MHz (4*F/sub sc/) allows 180 programmable taps to be implemented in a die area of 56.25 mm/sup 2/ in a 1 mu m TLM CMOS process. The device operates with 3.3- or 5-V power supplies.>
