摘要
电流反馈型运算放大器开拓了一种与双极互补工艺相结合的精巧电路拓扑结构，具有极佳的动态特性。该电路是８０年代末期模拟集成电路新进展的研究成果之一，有较高实用价值和一定理论价值。文章全面剖析了电流反馈运算放大器的拓扑结构特点和电路工作机理，综述了其性能特点、应用领域及相关研究课题。
The current feedback amplifier(CFA)expleits clever circuit topologies,which,in conjunction with complementary bipolar process,can achieve optimal dynamic properties. hevel-oped in late 1980’s,the CFA is of practical and theoretical value to the progress in anolog IC's. The circuit topology,theory of operation, performances and features of the CFA are examined.Its applications and development prospects are also investigated.
