Abstract
A cost function generator circuit includes memory terms each receiving one or more input signals, and each providing inphase and quadrature output current signals. The inphase and quadrature output currents of the memory terms are summed to provide combined inphase and quadrature output currents, respectively. Transimpedance amplifiers are provided to transform the combined inphase and quadrature output currents into an inphase output voltage and a quadrature output voltage.
