I'm drawing an equivalent circuit of a Triode (Vacuum Tube) using circuitikz
. Here is my code:
\ctikzset{tubes/width=2.8, tubes/height=4, tubes/fill=cyan, tubes/thickness=4}
\ctikzset{resistors/scale=1.1, inductors/scale=1.2}
\begin{circuitikz}
\draw (0,0) node (start) {}
++(0,2+\ctikzvalof{tubes/height})
to[L=$L_g$,o-] ++(2,0) to[R=$R_g$] ++(4,0)
node[triode,anchor=control] (Tri) {} ++(2,0)
(Tri.cathode) to[R=$R_c$,-] (Tri.cathode |- start) to[L=$L_c$,-o] ++(0,-2)
(Tri.anode) to[R=$R_a$] ++(0,4) to [L=$L_a$,-o] ++(0,2);
\end{circuitikz}
Now I'd like to draw parasitic capacitors with "curved/rounded" terminals. e.g. like this:
Is it possibile using
circuitikz
? Any idea?
