Abstract:

This paper presents the design of a highly energy efficient CMOS adiabatic driver (ob-driver). The proposed ob-driver uses an output stage with two inverters driven by a pre-driver circuit consisting of two differential cascode voltage switch (DCVS) logic cells. When implemented on a 0.13μm CMOS 1.2V technology, under the large capacitive loading condition, ob-driver performs better than the reference adiabatic circuit (sp-driver) in terms of the energy-delay product (34%), with active area which is only (9%) higher.

I. Introduction

Driving large capacitive loads in an energy efficient fashion is a major challenge in the design of high speed integrated circuits. Several fast drivers for large capacitive loads have been reported [1]–[16]. One way to improve energy efficiency is the use of low supply voltage [1]–[3]. However, inevitably this results in performance loss. To regain the performance loss in the low-voltage driver circuits, bootstrap technique has been employed [4]–[8]. Further, to improve energy efficiency of driver circuits with large capacitive loads, adiabatic technique has been used [9], [10]. Combination of bootstrap and adiabatic techniques has been reported in [11]–[13].
