摘要

本文提出了一种低电压、低功耗的可用于高频应用的CMOS OTA。采用台积电90nm CMOS工艺技术，模拟了差分输入单输出OTA的基本拓扑结构。仿真结果表明，该系统具有较高的带宽，带宽大于10GHz，功耗为0.721mW，跨导为-69.78dB。在1MHz频率下，100mV输入的总谐波失真为1.54%。本文对OTA进行了详细的参数分析。并对设计的OTA在三种不同工艺条件下进行了对比分析。

A Low Voltage Wideband CMOS Operational Transconductance Amplifier for VHF Applications

This paper presents a low voltage, low power CMOS OTA that can be used in high frequency applications. The basic topology using differential input single output OTA is simulated in TSMC 90nm CMOS process technology. The simulation results indicate high bandwidth, greater than 10GHz with 0.721mW power consumption and the transconductance of -69.78dB. The total harmonic distortion for 100mV input at a frequency of 1MHz is found to be 1.54%. The detailed parametric analysis of the OTA is covered in this paper. The comparative analysis of designed OTA at three different process technologies is also presented.
