Abstract
A CMOS low voltage Proportional-to-Absolute Temperature current reference is presented. The proposed circuit can work with supply voltages as low as 1.1 V. The circuit is designed in 90 nm CMOS technology for 2.2muA reference current at typical corner, 27 C, 1.2 V. The circuit has been extensively simulated across all possible combinations of MOSFET, Resistor, BJT, supply voltage and temperature variation corners. Simulation results have been given for a wide temperature variation from -40 C to 125 C and supply voltage variation from 1.1 V to 1.3 V.
