摘要

本文设计了一种应用于高精度模数转换器（Analog-to-Digital Converter，ADC）的低失调、低噪声、高精度带隙基准（BandGap Reference，BGR）芯片.针对传统架构的局限性，本工作提出了两项新技术：首先，采用反馈提升技术将运算放大器的失调电压和低频噪声等效到基准输出时减小至1/23；其次，提出了一种高精度基极电流补偿技术，降低不同工艺角和器件失配造成的基准输出偏移.设计的BGR芯片采用0.18 μm CMOS工艺实现，芯片面积0.142 × 0.258 mm

.测试结果表明，该BGR在1.2 V电源电压下输出0.6 V的参考电压，静态电流31 μA，0.1~10.0 Hz的积分噪声为2.79 μVrms，在-40~125 ℃ 温度范围内，基准源输出电压的温度系数是3.6 ppm/℃.

Abstract

A low-offset

low-noise

high-precision bandgap reference (BGR) chip for high-resolution analog-to-digital converters (ADC) is designed in this paper. In response to the limitations of traditional architectures

two new technologies are proposed. Firstly

feedback enhancement technology reduces the operational amplifier’s offset voltage and low-frequency noise to 1/23 when equival

ent to the reference output. Secondly

a high-precision base current compensation technique is proposed to reduce the reference output deviation under various corners and device mismatch. Implemented in 0.18 μm CMOS process

the proposed BGR occupies a chip area of 0.142 × 0.258 mm

.Measurement results demonstrate that the BGR generates a 0.6 V reference voltage under a 1.2 V power supply

consuming 31 μA quiescent current. The circuit achieves an integrated noise of 2.79 μVrms over 0.1~10.0 Hz and exhibits a temperature coefficient of 3.6 ppm/°C in the range of -40~125 ℃.
