A locally-clocked dynamic logic serial/parallel multiplier

Abstract

Locally-clocked (LC) dynamic logic is an asynchronous circuit technique that uses an event-driven controller to moderate a fine-grained pipeline consisting of latching dynamic logic gates. This paper extends the methodology to include feedback between successive pipeline stages. LC dynamic logic's ability to handle feedback is illustrated with the design of a 660 MHz serial/parallel multiplier implemented in a 1 /spl mu/m, 5 V CMOS process.
