那么有人能帮我把电阻器 R4 和 R5 像图中那样向左移动吗？提前谢谢 :)
答案1
路径组件始终绘制在命令的起点和终点的中间to。因此，如果您需要一段导线，然后是一个组件，则请准确说明：
\draw (a) -- ++(0.5,0) to[R] (b);
因此，作为教程要点，我将按照以下方式编写电路的运算放大器部分。请注意，只需更改以下代码即可更改电路的外观一个数字— 其余的也会效仿。所以如果你改变，\def\upwardshift{1.0}你的电路会更高，如果你改变，1.5你\draw (OA up) -- ++(-1.5,0) ...的电路会更宽，没有必须触碰任何其他数字或进行周围协调。
大量评论以显示用法。

\begin{document}
\begin{tikzpicture}[]
% everything will be relative to the position of the op amp chosen here.
% better use the `noinv input up` option than yscale=-1 so that the power supply
% anchors are not updown!
\node[op amp, xscale=-1, noinv input up](OA) at (0,0) {\ctikzflipx{\texttt{oa1}}};
% let's create the nodes above the op amp + and below op amp -.
% I am defining the shift here to reuse it for the symmetric one.
\def\upwardshift{1.0}
\draw (OA.+) to[short, -*] ++(0, \upwardshift) coordinate(OA up);
\draw (OA.-) to[short, -*] ++(0, -\upwardshift) coordinate(OA down);
% we want the resistor a bit off to the left; I'll mark the cable end position
% to reuse it on the other side. Just change the numbers here if you want
% to adjust positions, the others branches will follow suit.
\draw (OA up) -- ++(-1.5,0) coordinate(tmp) to[R=$R_4$] ++(-2,0) coordinate(r4 left)
% vertical connection in the same path to have a nice joined line, using
% the perpendicular coordinate system: vertically down (r4 left), horizontally (OA down)
-- (r4 left |- OA down)
% the other R
to[R=$R_5$] (tmp |- OA down) -- (OA down);
% connect the op amp output
\draw (OA.out) to[short, -*] (OA.out -| r4 left) coordinate(OA out);

现在将向上移位改为，0.75并将第一个显式连线改为2.5和：
这种技术使你的电路具有高度的可重复使用性——你可以建立一个丰富的子电路数据库，这些子电路可以轻松重新调整和重复使用。如果你使用显式坐标，你需要更改许多坐标来适应电路。
