摘要

提出了一种具有前馈补偿方案的两级运算跨导放大器的设计。在不使用米勒电容的情况下，所提出的OTA具有高增益和大带宽，而不影响良好的相位裕度。原型电路采用台积电45nm工艺设计。后布局仿真结果表明，在驱动8pF容性负载和从1 V电源消耗3.4 mW功率的情况下，增益为60.5 dB，单位增益频率为546.6 MHz，相位裕度为73°。

Wideband Operational Trans-Conductance Amplifier with Feed-Forward Compensation Technique

This paper presents the design of two stage operational trans-conductance amplifier (OTA) with feed-forward compensation scheme. Without using Miller capacitance, proposed OTA presents a high gain and large bandwidth without compromising good phase margin. The prototype circuit is designed using TSMC 45nm process. Post layout simulation results show a 60.5 dB of gain, 546.6 MHz unity-gain frequency, and 73° phase margin while driving 8pF capacitive load and consuming 3.4 mW power from 1 V power supply.
