Abstract:

This paper presents a curvature-compensated bandgap reference (BGR) circuit implemented in 0.35 /spl mu/m CMOS technology. The circuit delivers an output voltage of 1.09 V and achieves a temperature coefficient of 3.1 ppm//spl deg/C over [-20/spl deg/C, 100/spl deg/C] after trimming, a power supply rejection ratio of -80 dB at 1 KHz and an output noise level of 1.43 /spl mu/V/sqrt(Hz) at 1 KHz. The BGR circuit consumes a current of 37 /spl mu/A and the power supply ranges from 1.5 V to 3.3 V.
