摘要

带隙基准电压（BGR）是模拟电路中的关键元件。本文介绍了一种采用Cadence通用工艺设计套件（GPDK） 90 nm技术在亚阈值区域设计的BGR电路。采用级联编码技术消除通道长度调制效应，在较宽的温度和电源电压范围内获得稳定的输出电压。该电路产生的参考电压为344 mV，在室温下，电源电压为550 mV，功耗为94.64 nW。测量温度系数为8.337 ppm/OC，温度范围为- 45 OC ~ 170 OC，线性调节为0.017% /V。所设计的BGR电路可用于模拟应用。

Cascode subthreshold PTAT source bandgap voltage reference circuit

Bandgap Voltage reference (BGR) are crucial components in analog circuits. This paper introduces a BGR circuit designed in the subthreshold region using Cadence Generic Process Design Kits (GPDK) 90 nm technology. The cascoding technique is used to remove channel length modulation effect to get stable output voltage for a wider range of temperature and supply voltage. The proposed circuit produces a reference voltage of 344 mV, consuming 94.64 nW power at room temperature with a supply voltage starting from 550 mV. The temperature coefficient is measured to be 8.337 ppm/^OC within a temperature range of −45 ^OC to 170 ^OC with a line regulation of 0.017 %/V. The designed BGR circuit can be used in analog applications.
