Lidong Xing · International Electronic Elements · 2008
A bandgap reference circuit which is based on the bandgap voltage theory using for BLVDS transceiver system is designed with CSMC 0.5μm CMOS technology in this paper.This circuit features low temperature coefficient and high power supply rejection ratio.HSPICE simulation results show that the circuit can obtain a stable output voltage Vref=1.25V when supply voltage is 3.3V and temperature is 25℃.The temperature coefficient of output voltage is 20pm/℃ with a PSRR of-58.3 dB over temperature range from-45℃～+85℃.
