Circuitikz：包含运算放大器的完整方案

我请求任何人提供该图表的乳胶代码。

\begin{circuitikz}
\draw
(0,0) node[op amp] (op1) {}
(op1.-) to[short,*-*] ++(-0.8,0)
to [R,l=$R_1$,*-*] (-3.8,0.5) node(ex){}
to [short,*-o] ++ (-0.5,0) coordinate(ex1)
(op1.-) to[short,*-] ++(0,1.0) coordinate (leftC)
(op1.+) to ++(0,-1) node[cground]{}
(op1.-) to[short,*-] ++(0,1) coordinate (leftR)
to[R,l=$R_2$] (leftR -| op1.out)
to[short,-*] (op1.out);
\draw %----------------------------------------------Change

(op1.out) to[R,l=$R$,o-*] (op2.-)
(op2.-) to [short,-*] ++(0,1.5) coordinate (leftC2)

我已经写了上面的代码。我无法在一张图中画出 6 个运算放大器，一个运算放大器需要反转。

答案1

像这样？

在此处输入图片描述

我分三步绘制上面的图像：

  • 第一步，我重新绘制了运算放大器的主链，在它们的位置我使用了相对坐标，并定义节点锚定在它们的负输入端。
  • 第二步是添加输出运算放大器，命名为 op5，及其反馈环路。它op3通过使用选项位于运算放大器下方node distance。
  • 最后一个是反馈运算放大器，名为op6，并将反馈环路连接至链中的第一个运算放大器（op1）。
