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 $G$

void amplifier::calcNoiseAC ( nr_double_t ) [virtual]

Reimplemented from qucs::circuit.

Definition at line 116 of file amplifier.cpp.

void amplifier::calcNoiseSP ( nr_double_t ) [virtual]

Reimplemented from qucs::circuit.

Definition at line 73 of file amplifier.cpp.

amplifier::CREATOR ( amplifier )

void amplifier::initAC ( void ) [virtual]

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.

Reimplemented from qucs::circuit.

Definition at line 95 of file amplifier.cpp.

void amplifier::initSP ( void ) [virtual]

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

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