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