Analysis and design of CMOS resettable C-elements

This paper reviews existing reset schemes for the Muller C-element, one of the main primitives in asynchronous paradigms. Using a mathematical-based method and with the help of pass-transistor logic, an efficient implementation is developed that yields better performance. Simulations with a standard IBM 130-nm CMOS process, confirm that the proposed design achieves substantial improvement over existing implementations with respect to throughput, energy, and area.
