Abstract

Multiplication is frequently the speed-limiting function in digital signal processing systems. High-speed hardware multiplier ICs can therefore greatly enhance the throughput and bandwidth of many digital systems. In this paper, the design, fabrication, and performance of GaAs parallel multipliers are discussed. The largest of these circuits, an 8/spl times/8 bit multiplier, has 1008 gates, and is by far the most complex GaAs IC demonstrated today. This multiplier forms the 16 bit product of two 8 bit input numbers in 5.25 ns. This corresponds to an equivalent gate propagation delay of 150 ps/gate. The power dissipation ranges between 0.6-2 mW/gate.
