Abstract

In a threshold logic circuit, digital input signals are weighted and summed up and then the sum of weighted digital signals is compared with a threshold value. The threshold logic circuit comprises a plurality of current switching circuits and means for summing up the output currents from the current switching circuit. The weights for the input signals are changed by controlling supply currents to the current switching circuits.
