Given all the considerations required for getting a high-speed design to work, you might want to do something else.
Unless you're building a simple circuit with a few components on a breadboard, you're going to need a PCB. Let's face it, every electronic design has at least one. The design considerations for getting a high-speed design to work in the real world are so many that you might decide on a different career. You have to deal with signal integrity, power integrity, heat dissipation, impedance, mechanical issues, and the worst of all, time to market.
Signal integrity expert Dr. Howard Johnson presents a course in PCB design from which I've taken the questions for this week's quiz. Fundamentals of PCB Design runs for about 50 min. It's available at no cost. You just have to register and log in. If you're already registered at EE Times, then your login credentials will work.
As always, answers appear on the last page.
1. To maximize signal quality, which parameter should me keep as consistent as possible within any PCB design?
- Trace width
- Trace length
- Characteristic impedance
- All of the above
