Abstract :
A low voltage bandgap reference (BGR) in CMOS technology, with high power supply rejection ratio (PSRR) is presented. The proposed circuit uses a regulated current mode structure and some feedback loops to reach a low voltage, low power and high PSRR voltage reference. The circuit was designed and simulated in 0.25 um CMOS technology, with a power supply of 1 volt. The results show PSRR is below -70 dB at 1 MHz and the output voltage variation versus temperature (0-70) is less than 0.3%. This circuit shows robustness against process variation.
