摘　　要：采用双运放设计了一种指数型电压驱动电路,该电路的特点是不论电路的初始状态如何,都可以随着时间推移以指数函数的形式收敛至目标电压数值,和单运放组成的跟随器电路相比,兼具运放跟随器的高驱动能力的同时,对于短时高频的噪声也具有较好的抗噪性,可以作为电源电路或基准源电路的输出驱动使用。This paper uses dual op-amps to design an exponential voltage drive circuit.No matter what itsinitial states is,it can convergence to the target with an exponential regular.Comparing with the follower composed of a single op-amp,it has a high driving ability and a good noise immunity for short-term high-frequency noise,and can be used as the output driver of the power supply circuit or reference source circuit.
