在 CircuiTikZ 中更改 PMOS 的外观

我正在画一个由大量 PMOS 晶体管组成的电子电路。它还具有两条路径相交的节点，我用实心圆圈标记这些节点。问题是我使用的是至[Tpmos]用于绘制晶体管，并且栅极中的填充圆看起来与那些节点填充圆完全相等。

我怎样才能改变 PMOS 晶体管的外观，使得栅极填充的圆圈显示为空白圆圈？

这是一个 MWE：

\documentclass[convert={density=600}]{standalone}
\usepackage{circuitikz}
\standaloneenv{circuitikz}
\begin{document}

\begin{circuitikz}[american currents]
    \draw 
    (0,0) to[Tpmos, n=mp1] (0,2)
    (0,2) to[short] (1,2)
    (mp1.gate) to[short] ++(0,1) to [short, -*] ++(1,0);
\end{circuitikz}

\end{document}

结果如下：

问题是我希望 PMOS 门看起来与节点不同。也许可以通过用白色而不是黑色填充 PMOS 门的黑色圆圈来实现。

先谢谢了！

有点蛮力的方法。查看/usr/share/texlive/texmf-dist/tex/generic/circuitikz/pgfcirctripoles.tex，复制并修改绘制圆圈和引导线的内容：

          \anchor{D}{

看起来工作量很大，但实际上修改很小：

-           \pgfpathmoveto{\pgfpoint
-               {\pgfkeysvalueof{/tikz/circuitikz/tripoles/pmos/gate width}\pgf@circ@res@left}
+           \pgfpathmoveto{\pgfpoint %%% changed here to shorten the lead not to cross the circle
+                            {\pgfkeysvalueof{/tikz/circuitikz/tripoles/pmos/gate width}\pgf@circ@res@left-2*\pgfkeysvalueof{/tikz/circuitikz/nodes width}*\pgfkeysvalueof{/tikz/circuitikz/bipoles/length}}
                {\pgf@circ@res@up+\pgf@circ@res@down}}

用于电线和：

-           \pgfusepath{draw,fill}      
-
+                        % removed the fill here 
+           \pgfusepath{draw, }

进行填充。

也许可以通过一些很好的修补咒语来实现etoolbox...现在我看到它，我真的更喜欢新版本，所以也许只需修改原始文件并将其放入本地texmf树中就可以了。

顺便说一句，似乎栅极引脚的位置并不完全在网格上。如果您这样做：

\draw 
    (0,0) to[Tpmos, n=mp1] (0,2)
    (0,2) to[short, *-] (1,2)
    (mp1.gate) to[short] ++(0,1)
    to [short] ++(1,0)
    ;

您将摆脱那个不在连接中心的可怕的连接点......

现在有更好的解决方案！只需添加

\ctikzset{tripoles/pmos style/emptycircle}

到你的 circuitikz 环境。来源：https://github.com/circuitikz/circuitikz/issues/238#issuecomment-507619630
