- Abstract
- In this paper, we propose a novel toroidal current probe embedded in multi-layer printed circuit boards (PCBs) for electrostatic discharge (ESD) detection. The proposed current probe consists of an inner via-array, bridge lines, and an outer via-array, which surround an ESD current path and form a toroid to detect an ESD current. A transfer impedance between a port injected an ESD current and the proposed current probe is used for analysis of an ESD current coupling. Through experimental measurements, we verified the proposed current probe by comparison with a conventional current probe.
