A Novel High PSRR Bandgap Over a Wide Frequency Range

摘要：

This paper describes a novel bandgap reference with high PSRR over a wide frequency range. The design utilizes an internally regulated supply voltage without high gain feedback loop. Thus improve PSRR even at high frequency. Additional transistors are added to further improve supply rejection and minimize the second order effect. The circuit is implemented in 0.25um CMOS technology. It generates a reference voltage of 1.262V which has a voltage variation versus temperature of 0.1％ from -20C to 90C. It has a PSRR of 85dB at 1kHz and still 64dB at 1MHz.
