摘　　要：测量微电流一般采用电流负反馈直流放大器完成Ⅰ－Ⅴ变换。本文介绍一种基于积分电路的微电流测量电路，能有效地降低噪声水平，具有结构简单的优点。The Ⅰ -Ⅴ conversion in microcurrent measurement is usually performed by current negative feedback DC amplifier. This paper introduces a current measurement circuitry based on integrating circuit which can reduce the noise level effectively and features simplicity of construction

关 键 词：微电流测量 噪声 积分型电路 电流测量
