SINGLE ENDED DOMINO COMPATIBLE DUAL FUNCTION GENERATOR CIRCUITS

摘要

In some embodiments, the invention includes a domino logic gate circuit having a domino stage (18) and a single ended domino compatible dual function generator (54). The domino stage (18) receives a domino stage input signal and provides a single ended intermediate signal (INT) as a function of the domino stage input signal (INT), the intermediate signal (INT) having a state. The generator (54) receives the intermediate signal (INT) and provides an out signal and an out* signal each having a state, wherein the out and out* signals have the same state during a precharge phase and have complementary states during an evaluate phase as a function of the state of the intermediate signal. In other embodiments, the invention includes domino logic gate circuit having a combined domino stage and dual function generator. The domino stage is to receive a domino stage input signal. The dual function generator is a single ended domino compatible dual function generator to provide an out signal and an out* signal that each have a state and during a precharge phase, the out signal and out* signal each have the same state, and during an evaluate phase the out and out* states are complementary states as a function of the domino stage input signal without a logic X circuit and a logic X* circuit.
