Implemented of a Precision BiCMOS Bandgap Voltage Reference
LI Fu-de · Dianzi qijian · 2006
This paper is based on the analysis of the traditional bandgap reference. It has presented a new structure voltage reference, which adopts BiCMOS process and self-biased cascode current mirror circuit. We take use of Cadence software to simulate and verify it. The results have proved that the reference has low temperature coefficient and high power-supply rejection ratio. At present, it has a good prospect used in PWM.
