Interface circuits between adiabatic and standard CMOS circuits

Abstract

The clocking schemes and signal waveforms of adiabatic circuits are different from those of standard CMOS circuits. In order that adiabatic logic and standard CMOS circuits are co-existed on a single chip to utilize the strengths of various low-power approaches, the interface circuits that convert signals between adiabatic logic and standard CMOS circuits are demanded. This paper investigates design approaches of the low-power interface circuits in terms of energy dissipation. Several new low-power adiabatic-CMOS and CMOS-adiabatic interfaces are proposed. With TSMC 0.18μm CMOS technology, energy consumption of the proposed interface circuits has relatively large savings over a wide range of frequencies, as compared with previously reported circuits.
