Title

Improvements in GMI Probe Design for Time-Domain Transient Current Measurements

Abstract

Measurement techniques for time-domain transient currents are widely needed in many EMC applications. Demonstrated to have a lot of potential for this purpose, giant magnetio-impedance (GMI) probes are studied in this paper. Improvements in the probe design, including a balanced circuit for increased signal to noise ratio and an on-probe magnetic-field bias circuit, are proposed. These improvements in the probe design make the GMI probes more suitable for practical applications of time-domain transient current measurements.
