Abstract

Design techniques for realizing eight 32-tap transversal filters on a single-CMOS IC are discussed. The IC is capable of processing signals at a rate of 500 million multiplications and accumulations per second, while achieving a high dynamic range. The IC contains 32 sample-and-holds, a 32×32 analog multiplexer, eight 32-input summing amplifiers, and all of the needed control circuitry. The chip was fabricated using a standard CMOS, p-well process with double polysilicon. All of the necessary analog sampled-data and digital control circuits were realized on a 307×315 mil² die
