Detailed Description

A series or parallel 2-port resistor, derived from class spimp.

It has two real member parameters:

• R: resistance
• Temp: temperature, if different from the default temperature

Its resistance may be set during construction as well. Example:

    resistor r(100*Ohm); // a resistor named "r" with a value of 100 Ohms
 

Definition at line 173 of file elements.h.

Constructor & Destructor Documentation

resistor::resistor ( double r = 0.0 ) [inline, explicit]

Default constructor sets temperature to shadow device::T. Parameters: r   the resistance in standard units. Defaults to 0. Definition at line 192 of file elements.h.

resistor::resistor ( const abstract_real_parameter * r ) [inline, explicit]

Construct a shadowed parameter resistance. Parameters: r   pointer to the parameter to be shadowed. Definition at line 200 of file elements.h.

Member Function Documentation

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

Is an "active" noise source if its temperature is not the global T. Reimplemented from nport. Definition at line 238 of file elements.h.

void resistor::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 243 of file elements.h.

void resistor::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. Reimplemented from nport. Definition at line 244 of file elements.h.

resistor & resistor::set ( abstract_real_parameter * r ) [inline]

Set the resistance to shadow a parameter. Parameters: r   parameter of resistance in standard units. Definition at line 216 of file elements.h.

resistor & resistor::set ( double r ) [inline]

Set the resistance. Parameters: r   resistance in standard units. Definition at line 208 of file elements.h.

resistor & resistor::set_T ( abstract_real_parameter * t ) [inline]

Set the temperature to shadow a parameter. Parameters: t   parameter of temperature in standard units. Definition at line 232 of file elements.h.

resistor & resistor::set_T ( double t ) [inline]

Set the temperature. Parameters: t   temperature in standard units. Definition at line 224 of file elements.h.
