Transmission Line Parameters Extractor

Matlab implementation of patent Transmission-line simulators and methods (Patent# 8892414, Application# 12/713941).

Overview

• Project Website
• Bachelor Thesis (PDF)
  • Summary (PDF)
  • Summary (PPT)

In progress

Need to add:

• Resonance treatment
• Low-frequency conversion
• Passivity check
• Causality enforcement

Functions

• s2rlgc_t.m: Extract TL RLGC params from S params
• rlgc2s_t.m: Calculate S params from TL's RLGC params
• check_consistence.m: Accept the RLGC of the transmission line as input. Call rlgc2s_t.m to obtain the corresponding S parameters, and then call s2rlgc_t.m to re-extract RLGC. Comparing two sets of RLGC, they should be exactly the same.

Tests

1. test0.m: 500mil Single-line Transmission Line (Polar Si9000e)
2. test1.m: 500mil Coupled Transmission Line (Polar Si9000e)
   1. test1_1.m: (good) Using larger frequency intervals
   2. test1_2.m: (bad) Add randn noise to S, observe the impact on extracted-RLGC
   3. test1_3.mlx: (Very bad) Try to clean outliers or smooth of RLGC.
      • 使用实时编辑器任务清理杂乱数据并找到极值
      • 数据平滑和离群值检测
3. test2.m: 200mil Four-line Transmission Line (Ansys 2020R1)
   1. test2_1.m: (deprecated) removing singular frequencies
   2. test2_2.m: (deprecated) 10mm, with freq range 10M ~ 70G, HFSS Automatically use casual materials enabled.
   3. test2_3.m: HFSS_Welement -> ADS -> S
   4. test2_4.mlx: (not good) Try to clean outliers or smooth of RLGC. (Ansys 2020R1)
4. test3.m: 200mil 16-line Transmission Line (Ansys 2020R1)
   1. test3_1.m: HFSS_Welement -> ADS -> S
   2. test3_2.mlx: (bad) Try to clean outliers or smooth of RLGC. (Ansys 2020R1)
