Abstract

Current compensation for inverting logic gates is achieved by using a current mirror having a controlling leg equivalent to the input structure of the logic gate which is in the controlled leg. The controlling leg receives a reference voltage signal equal to the input signal to the logic gate which creates a leakage current. A plurality of controlled legs can be used with a single controlling leg to provide current compensation for a plurality of logic gates.
