Abstract
A CMOS exclusive OR/NOR gate is implemented with cross coupled transistors of the same conductivity type for simultaneously providing both logic signals. The logic gate is characterized by a pair of cross-coupled transistors of the same conductivity type coupled to the outputs thereof for selectively reinforcing the output logic level. One use of the exclusive OR/NOR gate is illustrated by coupling the gate to a switched logic circuit to provide a full adder. Transmission gate steering logic is used to further enhance circuit speed.
