Abstract :
A compact 64-tap programmable FIR filter, suitable for TV ghost cancellation, has been designed, fabricated and tested. The design uses carry-save add-shift (CSAS) multipliers, to achieve area efficiency, and an internally generated self-timed clock, to achieve timing efficiency. The prototype chip is implemented in a die area of 12.6 mm2 using a 0.8-μm CMOS process and can operate at up to 18 MHz, with a 5-V supply
