摘　　要：利用负反馈与程控模拟开关技术，较好地改善了使用光电耦合器件组成的隔离放大器所产生的非线性。By making use of the technique of negative feedback and program controlled analog switch, the nonlinear distortion produced by isolated amplifier with light electric coupler is improved and the amplifier gain is also adjusted.

关 键 词：线性放大器 负反馈 放大器 增益放大 隔离放大器
