Abstract :
This work proposes a new CMOS bandgap which can operate down to 0.95 V power supply. The reference voltage generated can be any value upto the power supply. The variation of this voltage with temperature can be made very small over a temperature range of 150degC degrees right down from 0degC upto 150degC. The circuit has been simulated using a UMC 0.18 mu process. The issue of the input common mode voltage has been circumvented by using a simplified differential pair.
