摘要

我们描述了一种简单的开关增益控制技术，用于改善功率限制下闭环放大器的稳定时间和峰值超调。我们考虑了两极放大器的重要特殊情况，并表明所提出的补偿方法优于基于分极的标准线性补偿。我们的结果得到了0.18μm CMOS工艺电路仿真的支持。

Switched-gain feedback amplifiers

We describe a simple switched-gain control technique for improving the settling time and peak overshoot of closed-loop amplifiers under power constraints. We consider the important particular case of two-pole amplifiers and show that the proposed compensation method out-performs standard linear compensation based on pole-splitting. Our results are supported by circuit simulations in a 0.18μm CMOS process.
