چکیده
This paper describes a new Bandgap Reference (BGR) architecture with low power consumption and high Power Supply Rejection Ratio (PSRR). Implemented in a 65nm CMOS technology, the circuit includes a pre-regulator, a current source and also digital validation for the bandgap voltage. The current consumption is below 4.9μA at 50oC, PSRR of -110dB@1kHz and -61.3dB@10MHz. The reference output voltage is 1.208V and the temperature coefficient is 3ppm/oC.
