摘要

采用TSMC 0.18 μm CMOS工艺

设计实现了一种低压、低失调、恒跨导的轨到轨运算放大器.运算放大器在保证输入级跨导在整个共模范围内恒定的前提下

采用轨到轨的折叠共源共栅输入级

输入管工作在亚阈值区

采用反馈式AB类输出级以实现轨到轨的输出摆幅

同时采用斩波稳定技术减小输入参考失调和噪声.电路工作在1 V单电源电压下

仿真得到119 dB的直流增益和5.6 MHz的增益带宽积.蒙特卡罗仿真结果显示失调电压分布的标准差为14 μV

输入噪声普密度为18.19 nV/√Hz.

Abstract

A rail-to-rail operational amplifier with low-voltage low-offset and constant transconductance is designed in TSMC 0.18 m CMOS process.The operational amplifier has a rail-to-rail folded cascode input stages

which ensures a constant transconductance over the available common-mode input range and all input transistors operate in sub-threshold region.A class-AB output stage with folded mesh feedback is used to achieve the rail-to-rail output range.The chopper stabilization technique is exploited to reduce the input referred offset and noise.The circuit is simulated in Cadence Spectre with a single 1 V supply.The simulation results show that the dc gain is 119dB and the GBW is 5.6 MHz.Montecarlo simulations demonstrate an offset distribution with 14 V standard deviation.The input noise spectral density is 18.19 nV/√Hz
