调整图形大小 - Beamer

我可以调整这张图片的大小吗Beamer？

\begin{frame}     
\begin{figure}[width=0.2\textwidth]
\centering
\begin{circuitikz}[american,node distance = 30pt]

\ctikzset{tripoles/mos style/arrows}

\draw (0,0) node[op amp,rotate = 90] (opamp) {}
    (opamp.-) to [short,-*] ++(-2,0) coordinate (CMm)
    to [short,-] ++(0,-1)
    to node[npn,anchor=emitter,yscale = -1] (Q1){} node[right,yshift = -0.7cm] {$Q_1$} ++(0,-1)

    (opamp.+) to [short,-*] ++(2,0) coordinate (CMp)
    to [R,l=$R_1$] ++(0,-1.5)
    to node[npn,anchor=emitter,yscale = -1,xscale = -1] (Q2){} node[left,yshift = -0.7cm] {$Q_2$} ++(0,0)

    (Q1.base) |- (Q1.collector)
    (Q2.base) |- (Q2.collector)

    (CMp) to [short,-] ++(0,3)
    to node[pmos,anchor=drain,yscale = 1,xscale = 1] (M2){} node[right,yshift = 0.7cm] {$M_2$} ++(0,1)

    (CMm) to [short,-] ++(0,3)
    to node[pmos,anchor=drain,yscale = 1,xscale = -1] (M1){} node[left,yshift = 0.7cm] {$M_1$} ++(0,1)

    (M1.gate) to [short,-,l = $oa\_out$] (M2.gate)
    (M1.source) to [short,-,l = $VDD$] (M2.source)
    (opamp.out) to [C,l=$C_{16}$] ++(0,1) |- (M2.gate)

    (Q1.collector) |- (Q2.collector) node[ground] {}

确实figure不做任何事情beamer，就像拥有一个center环境一样。

要缩放图形，您可以使用两种方法：

  1. 与scale（transform shape均为 Ti钾Z 选项):

    \begin{circuitikz}[american,node distance = 30pt, scale=0.7, transform shape]

  2. 使用scalebox--- 这也适用于不同的 x 和 y 比例，而前者将失败circuitikz（请参阅手册中的“已知错误和限制”部分）：您可以像这样包装您的电路：

    \scalebox{0.8}[0.7]{%
     \begin{circuitikz}[american,node distance = 30pt]
      ...
      \end{circuitikz}%
}
