Generalised threshold gate synthesis based on AND/OR/NOT representation of boolean function

This paper focuses on generalized threshold gates (GTGs) that implement boolean logic functions using elements with negative differential resistance (NDR). GTGs are capable of implementing boolean functions, however, no effective synthesis algorithms have been proposed so far. We present that GTGs can be effectively implemented using unate functions. Our synthesis algorithm ensures that the circuit implementing n variable boolean function consists of at most n+2 NDR elements and can be further optimized by reducing the number of switching elements.
