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 |

|
* speed of light in free space v0 = 2.9986e8 = 1/sqrt(L0*C0) |

* 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. |
