   \begin{circuitikz}[scale=1]
   \draw (0,8) node[xor port](xor1){}
(-4.25, 8.25) node[anchor=east] {A} %%input A
(-4.25, 7.75) node[anchor=east] {B} %%input B
(-4, 6.75) node[anchor=east] {$\text{C}_{in}$} %%input C_in
(2, 7.5) node[xor port] (xor2){} 
(xor2.out) node[anchor=west] {S}
(2, 5.5) node[and port] (and1){}
(2, 3.5) node[and port] (and2){}
(4, 4.5) node[or port] (or){}
(-4, 8.25) to[short, -*](-3, 8.25)-|(xor1.in 1)
(-4, 7.75) to[short, -*](-2.5, 7.75)-|(xor1.in 2)
(-4, 6.75) to[short, -*](0.6, 6.75)-|(and1.in 1)
(0, 6.75)-|(xor2.in 2)
(0, 8) to[short, -*](0.25, 8)-|(xor2.in 1)

(0.25, 8)--(0.25, 5.25)-|(and1.in 2)
(-3, 8.25)--(-3, 3.25)-|(and2.in 2)
(-2.5, 7.75)--(-2.5, 3.75)-|(and2.in 1)
(and1.out)-|(or.in 1)
(and2.out)-|(or.in 2)
(or.out) node[anchor=west]{$\text{C}_{out}$}
;
\end{circuitikz}
\end{figure}

我正在努力做到这一点，但不确定这种方法是否好。我在 Latex 中绘制电路方面还很陌生，我尝试添加非门，如下所示，但仍然令人困惑。

\begin{figure}[ht]
\centering 
\begin{circuitikz}[scale=1]
\draw (0,8) node[xor port](xor1){}
(-4.25, 8.25) node[anchor=east] {A} %%input A
(-4.25, 7.75) node[anchor=east] {B} %%input B
(-4, 6.75) node[anchor=east] {$\text{C}_{in}$} %%input C_in
(2, 7.5) node[xor port] (xor2){} 
(xor2.out) node[anchor=west] {Q}
(2, 5.5) node[and port] (and1){}
(2, 3.5) node[and port] (and2){}
(4, 4.5) node[or port] (or){}
(-4, 8.25) to[short, -*](-3, 8.25)-|(xor1.in 1)
(-4, 7.75) to[short, -*](-2.5, 7.75)-|(xor1.in 2)
(-4, 6.75) to[short, -*](0.6, 6.75)-|(and1.in 1)
(0, 6.75)-|(xor2.in 2)
(0, 8) to[short, -*](0.25, 8)-|(xor2.in 1)

(-1.5, 3.75) node[not port] (not1){}

(0.25, 8)--(0.25, 5.25)-|(and1.in 2)
(-3, 8.25)--(-3, 3.25)-|(and2.in 2)
(-2.5, 7.75)--(-2.5, 3.75)-|(not1.in 1)

(and1.out)-|(or.in 1)
(and2.out)-|(or.in 2)
(or.out) node[anchor=west]{$\text{C}_{out}$}
