ABSTRACT:
Aspects of the invention provide a fast one level zero-current-state XOR gate. An embodiment of the invention provides a first pair of differentially configured transistors and a level shifting resistor coupled to the first pair of differentially configured transistors. The one level zero-current-state XOR gate may also include a second pair of differentially configured transistors. A core of the XOR gate may be coupled to outputs of the first and the second pairs of differentially configured transistors.
