Application of Gunn effect to subnanosecond full adder and full subtractor

An n-bit parallel full adder and a full subtractor employing Gnnn-effect devices are proposed. The important feature is a high-speed carry generator utilizing transverse spreading of high field domains, whose operation is confirmed by computer study. The delay time of these circuits will be reduced to several hundred picoseconds.
