Beyond Design: Ground Bounce

February 22, 2018 | Barry Olney, In-Circuit Design Pty. Ltd.

Ground bounce, or more precisely, supply bounce, is the voltage produced between two points in the power delivery path. It is fundamentally related to the total inductance of the current path and shared return paths and the instantaneous surge current delivered by the power supply. Once again, we find that inductance is the covert enemy of the high-speed PCB designer. It is the primary cause of simultaneous switching noise and electromagnetic radiation. As edge rates continue to increase, the impact of intrinsic electrical characteristics become more pronounced. In this month’s column, Barry Olney looks at supply bounce and how to minimise the impact on high-speed digital circuits.

Frontline's InStack Viewer Helps Designers and Fabricators

February 22, 2018 | Real Time with DesignCon

Ben Quarles, software solultions business manager at Frontline, and Editor Andy Shaughnessy discuss the new InStack Viewer, which allows PCB designers and fabricators to investigate impedances, material properties, and other attributes of the correct stackup.
