Using SPICE to simulate the delay line circuit (first use 3x50ns units)

  • SPICE is not going too well. Hope to use the more powerful Mentor Graphics.

  • Back to Basics Approach:

  • The Probable source of our problems:

    • Incorrect units/equations given on manufacturers (Rhombus Industries) specs sheets.

      • Otherwise, things just don’t make sense!

  • From brute force method, we’ve got a system of equations.

    • Used Mathematica to solve

      • Testing solutions for the different L & C values, for an optimum set.

  • Things to do this week:

  • Continue to test possible L & C values for SPICE.

  • Test real delay lines (the samples are in).

  • From test results, decide which delay line values to use.

  • Get Shahab’s wedding gift for Friday.
