Performance Characteristics of Cmos Circuits in Sodel (silicon on Depletion Layer) Cmos over Conventional Cmos Technology

Abstract

In this paper, the switching performance of SODEL(silicon on depletion layer) CMOS is investigated with a view to realizing high speed and low power CMOS applications. Due to smaller parasitic capacitance , the propagation delay time in SODEL CMOS has been improved by up to 25% compared to that of conventional CMOS in 5 stacked NFET inverters at the same Vdd . Also, power-delay product is better by 30% in SODEL CMOS. Latch-up immunity for alpha particle irradiation in SODEL is found to be better than conventional CMOS. So SODEL CMOS device's circuit technology is expected to provide a better solution for low power system-on-chip applications.
