摘　　要：简述了高速运算放大器的进展，着重描述了８０年代末期基于互补双极工艺发展起来的电流反馈运算放大器的原理、特点、应用及制造工艺，分析了电流反馈运算放大器的小信号特性和大信号特性。Progress in high-speed operational amplifiers is briefly reviewed. Specifically,current feed-back operational amplifiers evolved in the late 80's are described with respect to the principle, characteristics, processes and applications. The small signal and big signal behaviors of the current feed-back operational amplifier are analyzed in particular.
