An Integer Linear Programming based method to identify current mode threshold logic functions is presented. The approach minimizes the transistor count and benefits from a generalized definition of threshold logic functions. Process variations are taken into consideration. Experimental results show that many more functions can be implemented with predetermined hardware overhead, and the hardware requirement of a large percentage of existing threshold functions is reduced.
