摘要
针对同相并联型差动输入运放的典型电路,分别在差模、共模信号下,应用小信号叠加原理,详细分析与讨论同相并联型差动输入运放的差模传输特性、共模抑制特性。从本质上揭示此类电路的突出优点。
Using small signal superposition principle,this paper analyses the differential-mode and common-mode rejection ratio characteristics of a differential Op-Amp with Noninverting input terminals in parallel,and basically reveals the noticeable advantages of the differential Op-Amp.
