YU Quan-dong, YANG Qi, ZHANG Guo-jun. Design of High Power Supply Rejection and Low Temperature Drift Voltage Bandgap Reference[J]. 2016, 33(4): 148-151.DOI:
a high power supply rejection and low temperature drift bandgap voltage reference is proposed for the application of system-on-chip. By introducing a pseudo-power supply and generating a voltage reference in a negative feedback loop
the power supply rejection of the reference is improved. This voltage reference provides a PSR of -177.6 dB at dc and -82.7 dB at 1MHz. Additionally
the temperature coefficient of this circuit achieves 5.76×10/℃ covering a range of -55~125℃.
