Tikz - 更改 pmos 的符号

Question

在这样简单的代码中出现的默认 pmos 符号

\documentclass{article}
\usepackage{tikz}
\usepackage{circuitikz}

\begin{document}
\begin{center}
\begin{tikzpicture}[american]

\ctikzset{tripoles/mos style/arrows}

\draw (0,0) node[pmos,anchor=source] (M1){}; 

\end{tikzpicture}
\end{center}
\end{document}

它的门上有一个粗体点。我找到了一些代码，可能是组件的定义这源文件，在行\pgfcircdeclaremos{pmos}。

无论是否使用该源文件，有没有办法删除点？

我想要获得一个与 nmos 符号完全相等的 pmos 符号（除了箭头不同），所以我想从 pmos 中移除点但不移除箭头。

Answer 1

以下是一个可能的解决方案。我已将pmos定义从pgfcirctripoles.sty文件复制到序言中，并注释掉了绘制圆圈的最后几行。就这样。
