Jiaguo Wu · Electronic Science and Technology · 2012
A High Precision CMOS voltage reference circuit is designed by the TSMC 40 nm CMOS process.Spectre simulation shows that the temperature coefficient is 10×10-6/℃ in the temperature range from-40 to 125.The change of the voltage reference is 0.42 mV,and the change rate is 0.23 mV/V in the power supply voltage range of 1.5~3.3 V.PSRR is 72 dB after using the cascode current mirror.
