Abstract

This paper presents a low power bandgap reference (BGR) with 573 mV average output voltage and 0.95-V minimum supply voltage. Here, the resistor ratio of two types of resistors that have opposite temperature coefficient (TC) realizes a second-order curvature compensation. In addition, to reduce the supply voltage we adopt a voltage divider, and we also employ proportional to absolute temperature (PTAT) voltage generators to reduce the resistor values for low power applications. The proposed BGR fabricated in 65-nm CMOS achieves an average TC of 57 ppm/degrees C from 0 to 100 degrees C with 8 samples. The power dissipation at room temperature is 78 nA and the power supply ripple rejection (PSRR) is -67 dB at DC with 1.2 V supply.
