摘要

本文提出了一种工作电压为1.5 V、功耗极低的线性CMOS亚阈值运算跨导放大器(LSOTA)的新结构。基于FGMOS技术，开发的OTA具有宽输入范围和小Gm，适用于实现低频模拟和单片连续时间滤波器。为了证明这一点，设计并仿真了一个低通二阶滤波器。该滤波器的功耗低于2 /spl mu/W，在1.5 V电源电压下，其拓扑结构可实现76 dB线性度，完全平衡输入动态范围高达1 Vpp。

A low voltage, highly linear CMOS OTA

This paper presents, a new configuration of linear CMOS subthreshold operational transconductance amplifier (LSOTA) working at 1.5 V with very low power consumption. Based on FGMOS technique, the developed OTA has a wide input range and small Gm, suitable for implementing low frequency analog and monolithic continuous-time filters. For demonstration a low pass second order filter was designed and simulated. The power consumption of the filter is less than 2 /spl mu/W and the topology achieves 76 dB linearity for fully balanced input dynamic range up to 1 Vpp at 1.5 V supply voltage.
