Detailed Description

The superclass for all device classes.

The main duties of class device are to:

(1) hold the global state variables:

• device::f (the current frequency)
• device::T (the default temperature)
• device::Z0 (the normalization impedance)

(2) set a unique id tag for each device created.

class device is an abstract class. It will never be instantiated directly.

Member Data Documentation

parameter device::T = 300 * Kelvin [static]

Global temperature. The default is set in nport.cc. Controls the temperature used for device calculations. It must be set to the desired temp. It is a parameter, so it may be set to shadow another parameter variable. Many devices have their own temperature variable which will override device::T if desired. Definition at line 54 of file nport.cc. Referenced by mixer::analyzer::calc_X().

parameter device::Z0 = 50 * Ohm [static]

Global normalization impedance. The default is set in nport.cc. Sets the normalizing impedance used for S matrix calcs. It is a parameter, but should not be set to shadow another. It may be useful to have other parameters shadow it, however. ALL RESPONSE CALCULATIONS PERFORMED BY CIRCUIT ELEMENTS (DERIVED FROM CLASS nport) MUST USE THE VALUE OF device::Z0 Definition at line 55 of file nport.cc.

unsigned long device::devcount = 0 [static, private]

Counter of total number of devices created. Used to set device::id. Definition at line 52 of file nport.cc.

parameter device::f = 0.0 [static]

Global frequency. The default is set in nport.cc. Controls the frequency used for all device calculations. It must be set to the desired freq. It is a parameter, so it may be set to shadow another parameter variable, or may in turn be shadowed by another parameter. Definition at line 56 of file nport.cc.

const unsigned long device::id

A unique serial number or id tag for this device instance. Definition at line 113 of file device.h.

state_tag device::last_state [protected]

Keep track of the last operating state where this device was calculated. Definition at line 109 of file device.h.
