void capacitor::calcAC ( nr_double_t frequency ) [virtual]

AC model.

Capacitor (capacitance $C$ ) is modelized by its $Y$ matrix:

$Y=\begin{pmatrix} 2j\pi f C & -2j\pi f C \\ -2j\pi f C & 2j\pi f C \end{pmatrix}$

Parameters:

[in] frequency frequency used for AC simulation

Reimplemented from qucs::circuit.

void capacitor::calcHB ( nr_double_t frequency ) [virtual]

Reimplemented from qucs::circuit.

void capacitor::calcSP ( nr_double_t frequency ) [virtual]

Compute S parameters.

$S$ parameter are computed from admitance, therefore $S$ matrix of a capacitor of capacitance $C$ is:

$S=\begin{pmatrix} \frac{1}{1+4j\pi fCZ_0} & \frac{4j\pi fCZ_0}{1+4j\pi fCZ_0} \\ \frac{4j\pi fCZ_0}{1+4j\pi fCZ_0} & \frac{1}{1+4j\pi fCZ_0} \end{pmatrix}$
