有没有什么办法可以让线条粗细均匀?
\documentclass[border=2mm]{standalone}
\usepackage{circuitikz}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[
every node/.style={font=\sffamily},
smallckt/.style={/tikz/circuitikz/bipoles/length=0.8cm},
]
\draw
(0.5,1.5) coordinate (tailpos) to [short, *-] ++(0,0.1)
to [smallckt, american current source, invert, n=Ibiasn] ++(0,1)
to [short, -o] ++(0,0.1) node[above]{$V_{DD}$}
(0,0) to [Tpigfete, n=Qnpos] ++(0,1) |- (tailpos)
(1,0) to [Tpigfete, mirror, n=Qnneg] ++(0,1) |- (tailpos)
