CMOS adiabatic driver with bootstrap technique for driving large capacitive loads

Abstract

This paper presents the design of a highly energy efficient CMOS adiabatic driver (ee-driver). The proposed ee- driver uses an output stage with two bootstrap capacitors driven by a pre-driver circuit consisting of two differential cascode voltage switch (DCVS) logic cells. When implemented on a 0.13/nm CMOS 1.2V technology, under the large capacitive loading condition, ee-driver performs better than the reference adiabatic circuit (ab-driver) in terms of propagation delay (39%), the energy-delay product (39%), and active area (57%).
