High-Speed Noise and Grounding

More Black Magic with
Dr. Howard Johnson
 

This two-day class focuses on mixed-signal applications involving high-speed digital electronics used in conjunction with sensitive analog circuits such as radio receivers, GPS devices and cell phones. This course addresses the critical issues of noise and grounding that are seen in many advanced signal processing applications today, including avionics, telemetry and guidance systems.

The motivation for this course is described in the somewhat tongue-in-cheek article: Digital Engineers Don't Believe in EMC.

Main Topics

Mixed-signal isolation Isolated ground layout
Ground bounce (SSO) Cuts in ground plane
System-level grounding Jitter
Power filtering for PLL's System test
Flex circuit cross-hatch Coaxial shielding
Clock distribution Susceptibility
Asynchronous clock regions Electrostatic discharge
