Abstract
A high PSRR and low temperature coefifcient BiCMOS bandgap reference was presented. In the design, the cascade current mirror is used in the circuit, and the output of the OPAMP is used for the bias of itself and to drive the next stage, in the same time PTAT temperature compensate is carried out. In the design of the paper, the output voltage is 1.242 V, while the temperature is 25℃. With the temperature range of-40~120℃, the bandgap reference voltage difference is 10 mV, which demonstrates the 60×10-6℃-1 temperature ratio.关键词
