摘要

本文介绍了一种全差分双端超低电压(ULV) FGUVMOS运算跨导放大器(FGUVMOS- ota)，以及使用FGUVMOS- ota的Gm-C滤波器。OTA没有内部节点、轨对轨运行和动态负载。Gm-C滤波器的截止频率可调超过50年。这些电路可以在低至200毫伏的电源电压下工作。

Tunable ultralow voltage transconductance amplifier and GmC filter

This paper presents a fully differential dual-ended ultralow-voltage (ULV) FGUVMOS operational transconductance amplifier (FGUVMOS-OTA), and a Gm-C filter where the FGUVMOS-OTA is used. The OTA has no internal nodes, rail-to-rail operation and dynamic load. The cut-off frequency of the Gm-C filter is tunable over more than 5 decades. The circuits may be operated with supply voltages down to 200 mV.
