ECEN5224: High Speed Digital

High-speed digital design, signal integrity, and transmission line theory.

This page include lab reports for PCB created for ECEN5224 at CU Boulder for Spring 2026. Circuit simulations were done with Keysight ADS and Siemens Hyperlynx.

Sharing of lab reports were encouraged by the instructor (Prof. Eric Bogatin) for personal portfolio. Only a portion of the lab reports are released on this page (to not hinder future students’ learnings).

Some topics covered in this class include:

- Lumped-Circuit Model, and Real-Life RLC circuits
- Circuit Simulations with Keysight ADS and Siemens Hyperlynx
- Transmission Line Models
- Crosstalk (NEXT and FEXT)
- Discontinuties, Reflections (TDR), and Termmination Strategies
- Differential Pairs and Lossy Lines (Eye Diagrams)
- S-Parameter Models
