摘要：
Voltage reference with high PSRR (Power Supply Rejection Ratio) and thermal stability is of key importance to power management IC (integrated circuit). By building up a stable internal regulated supply and improving its circuit and layout design, especially that of matching, a bandgap reference with high PSRR was proposed. Simulation results showed that PSRR of the circuit at low frequency was 64dB, and the peak-to-peak output voltage variation was 7.2mV over -40 degrees C to 80 degrees C.
