18th IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems (DFT'03) A Digital and Wide Power Bandwidth H-Field Generator for Automatic Test Equipment Boston, Massachusetts November 03-November 05 ISBN: 0-7695-2042-1
Recent research on modeling timing jitter has raised a requirement for a predictable, high magnitude, uniform, and wide bandwidth H-field. In this paper, a novel H-field generator design methodology is proposed. It consists of a single layer air core solenoid and a digital power switch driver that takes advantage of low power, wide bandwidth, and big current-driven capability. With input overdrive voltage, the digital switch can drive rail-to-rail voltage with output current up to 16A and power bandwidth more than 3 MHz. This paper demonstrates a novel solenoid driver circuit to generate an accurate H-field by comparing digital and analog approaches and comparing the experimental data with the theoretical data.
