摘要

提出了一种改进的翻转电压从动器(FVF)，它能提供高效的ab类工作。改进后的电路具有输出和吸收大电流的能力，与以前的方法相比，它能够使输出节点相对于输入保持恒定的电压。这是通过非常小的功耗增加和非常小的附加器件实现的。给出了该结构的仿真结果，验证了所提出的操作。

Class AB low-voltage CMOS Voltage Follower

A modification of the flipped voltage follower (FVF) that provides efficient Class-AB operation is presented. The modified circuit has the capability to source and sink large output currents and, compared to previous approaches, it is able to maintain the output node at a constant voltage with respect to the input. This is achieved with a very small increase in the power dissipation and very small additional devices. Simulation results of this structure verifying the proposed operation are provided.
