Detailed Description

Ideal and linear amplifier

An ideal amplifier increases signal strength from input to output and blocks all signals flowing into the output. The ideal amplifier is an isolator with voltage gain $G$

AC model initialization.

Idem than DC model.

Reimplemented from qucs::circuit.

Definition at line 112 of file amplifier.cpp.

void amplifier::initDC ( void  )
virtual

DC model initialization. An ideal amplifier is characterized by the following Y-matrix:

\[ \begin{pmatrix} \dfrac{1}{Z_1} & 0 \\ \dfrac{-2}{\sqrt{Z_1\cdot Z_2}} & \dfrac{1}{Z_2} \end{pmatrix} \]

With $Z_1$ and $Z_2$ the impedance of the port 1 and 2 and $G$ the gain.

Initialize S-parameter simulation. An ideal amplifier is characterized by the following S-matrix

\[ S=\begin{pmatrix} \dfrac{Z_1-Z_0}{Z_1+Z_0} & 0 \\ \dfrac{4\cdot Z_0\cdot\sqrt{Z_1\cdot Z_2}\cdot G}{(Z_1+Z_0)\cdot(Z_2+Z_0)} & \dfrac{Z_2-Z_0}{Z_2+Z_0} \end{pmatrix} \]

With $Z_1$ and $Z_2$ the impedance of the port 1 and 2 and $G$ the gain.
