摘　　要：正向设计了一种适合于听觉神经刺激的可编程双相恒流脉冲发生器，它可根据耳聋患者的要求和不同的语音信号，控制刺激电流脉冲的幅度和宽度，以及脉冲之间的间隙。本文阐述了电路的设计要求和方法，并给出了实验结果。采用标准３μｍｐ阱ＣＭＯＳ工艺，在上海贝岭微电子制造有限公司流片。目前已成功地用于多道人工电子耳蜗接收刺激器中。A top-down design of a programmable biphasic constant-current generator for auditory nerve stimulation has been made. which is able to control the phase current and width.as well as the intervals be- tween stimulus current pulses according to the deaf’s desire and different speech signals.Techniques to design the circuit and some requirements are presented.Expetimental results are given. Using the standard 3-um p- well CMOS process.the device has been successfully fabricated and used in a receiver-stimulator for a multi- ple-channel artificial electronic cochlea.
