Abstract
A current-mode synapse multiplier circuit multiplies each of a plurality of pulse signals with each of a corresponding plurality of weight signals. The synapse multiplier includes a plurality of first switches each coupled to a corresponding pulse signal and the corresponding weight signal. An integral circuit is coupled to the first switches to receive the weight signals that pass through the first switches and integrates the sum of the weight signals that pass through the first switches over a period of time. A voltage-to-current (V-I) converter is coupled to the integral circuit to convert the integral of the sum of the weight signals that pass through the first switches into a current signal, wherein the current signal represents the sum of the multiplication products of each pulse signal and the corresponding weight signal. An external reset signal is coupled to the synapse multiplier through a second switch to reset the synapse multiplier.
