Paper Abstract

A high-speed GaAs transversal filter IC has been developed that contains in excess of 41,000 transistors which implements a finite impulse response filter for IR data stream SNR (S/N) enhancement in clutter rejection systems. The circuit contains an address controller in addition to a multiply/accumulate processor for interfacing with external memory and a register file for storing progammable filter coefficients (tap weights). Very-high-speed operation, as shown by a predicted clock rate of 160 MHz, is obtained through the utilization of a pipelined architecture and an advanced GaAs processing technology. The high-performance characteristics of this circuit permit it to be applied as a single serial processor to systems normally requiring parallel processing techniques.
