Efficiency of low-power design techniques in multi-gate FET CMOS circuits

Abstract

Energy dissipation, performance, and voltage scaling of multi-gate FET (MuGFET) based CMOS circuits are analyzed using product-representative test circuits composed of 10k devices. The circuits are fabricated in a low power MuGFET CMOS technology, achieve clock frequencies of 370-500MHz at VDD=1.2V, and operate down to the subthreshold region. Voltage scalability of MuGFET circuits is superior to sub-100 nm planar CMOS circuits due to excellent short-channel effect control.
