Voltage-Controlled Voltage Sources

  Equally simple is it to include voltage-controlled voltage sources in the circuit analysis. Fig. 3.3 shows a voltage-controlled voltage source where the node labels give the possible node configuration. The controlling nodes n1 and n2 can be any two nodes, and the output nodes pf1 and pf2 are either potential-nodes or floating-nodes.

A voltage-controlled voltage source brings another relation for node potentials.
\begin{gather}\varphi_{pf_1} - \varphi_{pf_2} = g(\varphi_{n_1} - \varphi_{n_2})
\end{gather}
The amplification factor of the voltage-controlled voltage source is g.
