Discover how PCB layout choices can dramatically alter S‑parameter measurements of high‑speed ESD protection devices—especially in the femtofarad range. Through 3D EM simulations and real‑world testing, this article reveals why accurate modeling and optimized test boards are essential for reliable high‑speed performance.

When your circuit misbehaves with unexplained noise and jitter, you're facing electromagnetic coupling. This practical guide walks engineers through identifying whether problems stem from differential or common mode issues, near-field or far-field effects, and provides a systematic debugging workflow to isolate sources, paths, and receivers—getting your design back on track.

Award-winning research reveals that advanced chip assembly faces unique ESD risks as dies stack closer together. 3D electromagnetic modeling shows discharge currents can exceed 2 amperes in picoseconds, potentially damaging sensitive die-to-die connections despite controlled cleanroom environments.

Watchdogs are essential system design components that reset systems for recovery. Originally standalone timer ASICs, they're now integrated into power management devices, voltage supervisors, and microcontrollers to enhance functional safety. This article explains various watchdog timers, their interactions, and design strategies for multiple watchdogs, particularly in functionally safe multicore systems requiring independence.
