Quasi-Static Current Measurement with Field-Modulated Spin-Valve GMR Sensors

Quasi-Static Current Measurement with Field-Modulated Spin-Valve GMR Sensors

A non-contact current measurement device comprised of a GMR sensor and a ferrite ring core was investigated. The sensor chip employed a high-sensitivity spin-valve full-bridge GMR sensor of which the direct output has non-negligible hysteresis and a limited linear range. By applying an AC modulation...
