    Abstract: In order to improve the accuracy and stability of bandgap reference output voltage, a bandgap reference circuit with high power supply rejection ratio and low temperature drift is designed based on 0.18um BCD technology. Based on the traditional bandgap voltage reference structure, this paper designs a current mirror cascade and a prereference circ... Show More
