摘要
本文对电流反馈运算放大器在反相输入及同相输入两种情况下的闭环负反馈特性进行系统分析，对闭环带宽、闭环增益的关系及主要参数对闭环特性的影响作全面讨论。用SPICE模拟结果对理论分析加以验证。
The closed-loop negative feedback characteristics of current feedback operational amplifier are systematically analyzed. The relationship between closed gain and bandwidth as well as primary parameter effects on closed-loop characteristics are discussed. SPICE simulation results are given to verify the theoretical analysis.
