我怎样才能用 绘制这个电路CircuiTikz
?我找到过很多类似的电路,但这是我第一次使用这个包。
我正在使用 Beamer,我想首先显示一个没有 R 的框架,然后显示一个与 C 并行的带有 R 的框架。
这是我找到并部分修改的代码:
\begin{circuitikz}
\draw (6,2) node[op amp] (opamp2) {}
(4,2.5) to [ground] (opamp2.-)
(4.8,1) node [ground] {}to [short] (opamp2.+)
(opamp2.-) -- +(0,1.5) to[C] +(2.3,1.5) -|
(opamp2.out) to [short,-o] (8,2)node[right]{};
\end{circuitikz}

大约一年前(可能更早),我对类似的问题给出了以下解释:

此代码距离您想要的内容只有两个元素。如果您在阅读此说明后在绘图中遇到困难,请提出新问题以显示您遇到的问题。在绘图中,circuitikz
包文档会大有帮助。
附录(已编辑): 让我通过两个步骤制作您的图像:第一步重复上图,第二步添加电阻器:
\documentclass[margin=3mm]{standalone}
\usepackage{circuitikz}
\begin{document}
\begin{circuitikz}[every pin/.append style={align=left, text=blue}]
\draw
(0, 0) node[op amp] (opamp) {}
(opamp.-) to[short,-o] ++(-1, 0)
(opamp.-) to[short,*-] ++(0,1.5) coordinate (leftC)
to[C] (leftC -| opamp.out)
to[short,-*] (opamp.out)
to[short,-o] ++ (0.5,0)
(leftC) to[short,*-] ++ (0,1) coordinate (leftR)
to[R] (leftR -| opamp.out)
to[short,-*] (leftC -| opamp.out)
(opamp.+) -- ++ (0,-0.5) node[ground] {};
\end{circuitikz}
\end{document}
