Design of Bandgap Voltage Reference Source Based on Low Voltage and High PSRR
This paper describes the design of a bandgap voltage reference source with low voltage and high power suppression ratio(PSRR),analyzes the characteristics of the bandgap voltage reference source,and combines the limitations of the original circuit design to design a bandgap voltage reference source circuit structure with low voltage and high PSRR.Simulation analysis shows that the simulation results are consistent with the theoretical analysis results,and the designed circuit has good applicability in low-voltage analog circuits and digital signal processing systems.
