Abstract : A multiplying system for complex numbers using four three-stage 4 x 4 bit 2's complement multipliers and a modified adder and subtractor. Two of the 2's complement multipliers are fed to the subtractor which produces a 9 bit output representing the real term of the complex product and the other 2's complement multipliers are fed to the adder which produces a 9 bit output representing the imaginary term of the complex product. Each of the 3-stage 2's complement multipliers are modified from prior art multipliers to effect the two most significant bits. The unique adder and subtractor as well as the multipliers are implemented with universal logic gates consisting of cascode circuit components resulting in five gating stages for the complex multiplying system.
