Abstract

This study presents a novel design approach combining wave pipelining and self reset logic, which provides an elegant solution at high-speed data throughput with significant savings in power and area as compared with other dynamic CMOS logic implementations. To overcome some limitations in SRL art, we employ a new SRL family, namely, dual-rail self reset logic with input disable (DRSRL-ID). These gates depict fairly constant timing parameters, specially the width of the output pulse, for varying fan-out and logic depth, helping accommodate process, supply voltage, and temperature variations (PVT). These properties simplify the implementation of wave pipelined circuits. General timing analysis is provided and compared with previous implementations. Results of circuit implementation are presented together with conclusions and future work.
