BJTdriver -- 24inch lossy line -- DiodeCircuit
|
||||
|
||||
* This unclassified circuit is from Raytheon, courtesy Gerry Marino.
|
||||
* It consists of a BJT driver connected by a 24 inch lossy line to a
|
||||
* passive load consisting mostly of diodes. Each inch
|
||||
* of the lossy line is modelled by 10 LRC lumps in the Raytheon
|
||||
* model.
|
||||
|
||||
* The line parameters (derived from the Raytheon input file) are:
|
||||
* L = 9.13nH per inch
|
||||
* C = 3.65pF per inch
|
||||
* R = 0.2 ohms per inch

* From neug1, Mosaic aluminum lines. 2um thick, 11um wide. Assuming

* 10um above the ground.

* Material: aluminum; resistivity (sigma) = 2.74uohm-cm = 2.74e-8 ohm-m

* Dielectric: SiO2, dielectric constant (epsilon) =3.7

* Line parameter calculations:

* C = epsilon*epsilon0 * A / l
|

* C = 3.7*8.85e-12 * 11e-6 * 1(metre) / 10e-6 = 36.02e-12 F/m

|

|

* => L0 = 1/C0*v0^2
|

* L0 = 1/(12.65e-12 * 8.9916e16) = 1/113.74e4 = 0.008792e-4 H/m

* Subcircuit conv2wtwentyinch
|
||||
* conv2wtwentyinch is a subcircuit that models a 2-conductor transmission line with
|
||||
* the following parameters: l=9.13e-09, c=3.65e-12, r=0.2, g=0,
|
||||
* inductive_coeff_of_coupling k=0.482, inter-line capacitance cm=1.8e-12,
|
||||
* length=20. Derived parameters are: lm=4.40066e-09, ctot=5.45e-12.
|
||||
*
|
||||
* It is important to note that the model is a simplified one - the
|
||||
* following assumptions are made: 1. The self-inductance l, the
|
||||
* self-capacitance ctot (note: not c), the series resistance r and the
|
||||
* parallel capacitance g are the same for all lines, and 2. Each line
|
||||
* is coupled only to the two lines adjacent to it, with the same
|
||||
* coupling parameters cm and lm. The first assumption imply that edge
|
||||
* effects have to be neglected. The utility of these assumptions is
|
||||
* that they make the sL+R and sC+G matrices symmetric, tridiagonal and
|
||||
* Toeplitz, with useful consequences.
|
||||
*
|
||||
* It may be noted that a symmetric two-conductor line will be
|
||||
* accurately represented by this model.
