A novel current reference in 45nm cmos technology

Abstract

In this paper a novel CMOS temperature and supply voltage independent current reference has been proposed. This design is based on the subtraction of two scaled version PTAT (proportional to absolute temperature) currents to provide a temperature independent current reference. The design was simulated with Spectre, and implemented in 45nm CMOS technology. Simulation results shows that the proposed current reference achieves temperature coefficient of 22ppm/0C against temperature variation of -400C –1200C and line sensitivity of 337ppm/V against supply variation of 0.6–1.8V, while consuming 135uW from 1.8V supply and occupying 5184um2
