摘要

提出了一种带电流控制电路(CCC)的CMOS带隙基准电压(BGR)设计方案，并利用Silterra 0.13μm CMOS技术进行了仿真。CCCs设计用于在较低和较高温度下抑制总电流。所提出的BGR利用曲率校正电流发生器来补偿在扩展温度范围内的输出电压变化。该电路在−50℃~ 125℃的工作温度范围内，输出电压为1.1833V，变化幅度为329μV。在2.5 V的供电电压下，BGR电路被证实能够比没有CCC的电路节省12.6%的功耗。

A CMOS bandgap voltage reference with current-control circuits for the extended operating temperature range

A CMOS bandgap voltage reference (BGR) with current-control circuits (CCC) design is proposed and simulated using Silterra 0.13μm CMOS technology. The CCCs is designed to suppress the total current at lower and higher temperatures. The proposed BGR utilizes curvature-corrected current generators that compensate the output voltage variation in the extended temperature range. The proposed circuit generates an output voltage of 1.1833V with a variation of 329μV within the temperature range of −50°C to 125°C. With a 2.5 V supply voltage, the BGR circuit was verified able to save power consumption by 12.6% compared with a circuit without the CCC.
