摘要 电路元块模型简称元块,包括耦合元块与控源元块,控源元块有比例受控源和积分受控源两种,运放的电路模型即为比例受控源。受控源电路(包括运放电路)有各种复杂多样的电路形式,其原理分析与电路求解是电路和模电课程的难点。将比例受控源拓展到积分受控源,并提出了受控源电路(含实际运放电路)的拟独立源分析法和理想运放电路的三层级解算法(基础模型法、单元拆解法和闭环公式法),丰富了电路的样式和求解方法;结合微分算子法统一了静态、稳态与暂态电路的表述与分析求解方法,丰富了电路原理的内涵,完善了电路的知识体系,有助于受控源和运放在工程中的应用。 The circuit metablock model,abbreviated as metablock,includes coupling metablock and control source metablock.There are two types of control source metablocks:proportional controlled source and integral controlled source.The circuit model of the operational amplifier is called proportional controlled source.Controlled source circuits(including operational amplifier circuits)have various complex and diverse circuit forms,and their principle analysis and circuit solution are difficult points in circuit and analog courses.This article extends the proportional controlled source to the integral controlled source,and proposes a quasi-independent source analysis method for controlled source circuits(including actual operational amplifier circuits)and a three-level solution algorithm for ideal operational amplifier circuits(basic model method,unit disassembly method,and closed-loop formula method),enriching the style and solution methods of circuits.The combination of differential operator method unifies the expression,analysis and solution methods for static,steady-state,and transient circuits,enriches the connotation of circuit principles,improves the knowledge system of circuits,and contributes to the application of controlled sources and operational amplifiers in engineering.
