CircuitTikZ 4 针 FET 符号

有人知道 CircuitTikZ 中自定义的 4 针/腿 FET 符号吗？类似这样的符号就完美了： enter image description here

原包装中有一个合理的部分，但这对于我的目的来说会更好

答案1

这可以通过一种非常丑陋的技巧来实现，即将 Gateline 移动到源极/漏极线上，并使用选项“nogate”抑制栅极连接的绘制：

\begin{circuitikz}
\ctikzset{tripoles/nigfetd/gate width/.initial=.5}%move gate over drain/source-line
\draw (0,0)node[nigfetd,nogate](t){};
\draw(t.G)++(0,0.35)coordinate(G1)--++(0.4,0){--++(0,0.25)};
\draw(t.G)coordinate(G2)--++(0.4,0){--++(0,0.25)};

\draw(G1)node[left]{$G_1$};
\draw(G2)node[left]{$G_2$};
\end{circuitikz}

enter image description here

谨致问候，Stefan

由于无法使用，这有点复杂\drawfetcore。
