Detailed Description

Creates a TRW 300 x 0.1 micron chip trasistor.

VD = 0.50 V ; ID = 5.0 mA ; VG = -0.431 V Model was obtained from Daniel Gallego.

Model includes effects of 0.7 mil gold bond wires each approximately 250 - 300 microns long as follows: 1 on the gate, 1 on the drain, and 4 on the source.

Member Function Documentation

void jpltrw300::recalc ( ) [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 fet.

void jpltrw300::remove_bond_wires ( )
 

Calling this option will cause model of bare, unbonded transistor to be used.

By default, wire bonds are included (see comment, above.)
