摘要
针对多个运放构成的复杂线性电路的已有分析方法运算效率不高的缺点,提出利用节点电压法,选取反相(同相)输入节点列写节点电压方程的分析方法。论文详述该方法的原理与典型应用,最后用仿真软件进行验证。与已有方法相比,该方法提高了求解由多个运放构成的复杂线性电路的运算效率。同时方法可靠、简便、易行。
For the lower efficiency of the existing analytical methods when solving the complicated linear circuit with many inte- grated operational amplifiers, the paper proposes node voltage equations by selecting the inverted or the non-inverted input nodes. The paper describes the principle and the typical application, and then the method is verified. Compared with the existing analysis method, it improves the efficiency when solving the complex operational amplifier linear circuit. At the same time the method is reli- able, simple and easy.
