摘要

本文提出了一种具有精确曲率补偿技术的新型带隙基准电压，可以完全补偿发射基电压的热非线性。该带隙电压参考电路采用VIS 0.15标准CMOS工艺，在−55°C至155°C的温度范围内，电源电压为1.8V，温度系数为1.03 ppm/°C。此外，该电路在1.8V ~ 3V电压范围内，超低频(<200Hz)、1kHz和10kHz时，电源抑制(PSR)水平分别为83dB、77dB、58dB，可实现0.02%/V的线路调节性能。

A Novel 1.03 ppm/°C Wide-Temperature-Range Curvature-Compensated Bandgap Voltage Reference

This paper proposes a novel bandgap voltage reference with an accurate curvature compensation technique for completely compensating the thermal nonlinearity of the emitter-base voltage. With VIS 0.15 standard CMOS process, the proposed bandgap voltage reference circuit achieves temperature coefficient of 1.03 ppm/°C over the temperature range from −55°C to 155°C with the supply voltage of 1.8V. In addition, the circuit achieves line regulation performance of 0.02%/V with the supply voltage from 1.8V to 3V and the power supply rejection (PSR) levels are 83dB, 77dB, 58dB at ultra-low frequency (<200Hz), 1kHz and 10kHz, respectively.
