The Rise (time) and Fall (time) of Delay Lines

Delay Line Update 8/04/03Ian Harnarine

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

Delay Line Update 8/04/03 Ian Harnarine

• 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.
