DDCVS Logic for Asynchronous Gate-Level Pipelined Circuits

Abstract

This paper proposes a new way of realizing the data paths for asynchronous domino logic gate-level pipeline styles. This novel approach improves the speed of the pipelines by preserving the latch-less feature of domino pipelines. In this work, the data paths of three asynchronous 16-bit adders based on APCDP, LP2/2, and HC-Hybrid pipelines are constructed using dual-rail domino cascode voltage switch (DDCVS) logic and simulated using cadence toolset in 90 nm technology. The adders based on DDCVS logic have exhibited higher performance and lower energy-delay square product compared to the adders based on domino logic. © 2021, Springer Nature Singapore Pte Ltd.
