Abstract :
A CMOS low voltage bandgap reference circuit is presented. The proposed circuit architecture enables it to work with supply voltages as low as 1.1 V. The circuit is designed in 90 nm CMOS technology for a typical bandgap output voltage of 611 mV. Simulation results show that generated bandgap output voltage varies from 600 mV to 626 mV 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 -40C to 125C and supply voltage variation from 1.1 V to 1.3 V.
