Open source circuit boards to understand SI, PI and EMI

— Abstract — We are all lifelong learners. The only difference between school and work is the relative balance between learning and doing, and the direction the money flows. If we do not continually learn, our skills will become obsolete in a few years. We learn by studying books, lectures, and videos, but we understand by doing. This includes solving problems, performing simulations, and conducting hands-on measurements. Our group at CU Boulder has developed a series of low-cost, open-source circuit boards used in our PCB design and signal integrity courses to provide undergraduates and graduate students with hands-on experience in understanding how physical design influences noise in circuits. The first series of boards will be released in December 2025. Some of the design principles these boards demonstrate will be presented in this talk.

— Biography — Prof Eric Bogatin received his BS in physics from MIT and PhD in physics from the University of Arizona, Tucson. After working in industry for 30 years at Bell Labs, Raychem, and Sun Microsystems, he started his own company, which was acquired by Teledyne in 2012. He transitioned to teaching full-time and is currently on the faculty at CU Boulder, where he teaches signal integrity to graduate students and systems engineering in the senior design capstone program. He is a Fellow with Teledyne and the technical editor of the Signal Integrity Journal.
