1. Delay Line Update 8/04/03 Ian Harnarine NICADD Weekly Meeting The Rise (time) and Fall (time) of Delay Lines

2. Delay Line Update 8/04/03 Ian Harnarine Using SPICE to simulate the delay line circuit (first use 3x50ns units)

3. 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:

4. Delay Line Update 8/04/03 Ian Harnarine 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.

5. Delay Line Update 8/04/03 Ian Harnarine 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. Shahab
