本文介绍了一种专门用于脑-机接口(BCI)的双极脑电放大器的研制。放大器的设计原理是以差动放大器为基础，辅以多个增益放大单元。放大器的增益很容易被修改，以放大其他生物电势信号。设计的电路满足低功耗、高增益、低频响的要求。
This paper describes the development of a bi-polar EEG amplifier designed specifically for use in a brain-computer-interface (BCI). The design principle of amplifier is base on a differential amplifier followed with multiple gain amplifier units. The amplifier gain is easily modified to amplify other biopotential signals. The design circuit meets the requirement of low power consumption, high gain and low frequency response.
