Utilising dynamic logic for low power consumption in asynchronous circuits

Dynamic logic offers compact, fast solutions for synchronous design. Asynchronous design methodologies which conform to the bounded-delay model can also utilise dynamic logic for combinational circuits obtaining similar benefits to the synchronous case. To achieve these benefits, the logic is held in precharge until it is required and the evaluation phase is completed during a handshake communication action. The resultant power consumption is low since the input capacitance is far smaller than equivalent static CMOS circuits and spurious transitions in the computation are removed
