本文介绍了一种高性能的跨导放大器，专门设计用于电触觉（皮肤电）刺激。它可以在输出端产生高达±600 V的电压，这将允许使用各种刺激波形更彻底地研究与指尖刺激相关的心理生理表现。该设计具有高达20 mA/V的跨导，8.8-MΩ输出电阻，并可提供高达±20 mA的输出电流。给出了一个完整的原理图，并讨论了操作理论和安全问题，以及实现设计的性能和降额图。
This article describes a high-performance transconductance amplifier specifically designed for electrotactile (electrocutaneous) stimulation. It enables voltages up to ±600 V to be produced at the output which will allow the psychophysiological performance associated with stimulation of the fingertip using various stimulation waveforms to be studied more thoroughly. The design has a transconductance of up to 20 mA/V, an 8.8-MΩ output resistance, and can provide output currents up to ±20 mA. A complete schematic diagram is presented along with a discussion of theory of operation and safety issues as well as performance and derating plots from the implemented design.
