Detailed Description

A two port parallel RLC device, derived from class spimp.

The impedance of a parallel_RLC is that of a parallel resistor, capacitor, and inductor. The order of the components is mathematically irrelevant, since the admittance is the sum of the individual admittances, and the scattering and noise correlation matrices are functions only of the admittance.

The resulting admittance of the parallel RLC combination is connected either in series with or in parallel with the two ports, as described for class spimp.

parallel_RLC has four real member parameters:

The RLC values may be set during construction as well. Example: 
    parallel_RLC a(.01*Ohm, .2*Nano*Henry, 1*Pico*Farad);

This device may be useful if you need a simple but more accurate model of some real lumped circuit element.

Member Function Documentation

const nport::data_info & parallel_RLC::get_data_info ( ) [inline, virtual]
 

Is an "active" noise source if its temperature is not the global T.

Reimplemented from nport.

Definition at line 637 of file elements.h.

void parallel_RLC::recalc ( ) [inline, private, virtual]
 

The function for calculating sdata.

recalc() should do the following:

  • (1) Read device::f, device::Z0, and, by default, device::T to get the operating conditions for the response calculation.
  • (2) Calculate the S, C, and B matrix values and store them to nport::data, with all values normalized using device::Z0.
  • (3) Store the normalizing impedance to nport::data by calling data.set_znorm().

Reimplemented from nport.

Definition at line 654 of file elements.h.

void parallel_RLC::recalc_S ( ) [inline, private, virtual]
 

If the following function is implemented, it should only calculate the S matrix and B vector parts of data, leaving the C matrix part stale.
