Title:
DUAL MODE READOUT INTEGRATED CIRCUIT FOR MAGNETIC IMPEDANCE SENSOR
Document Type and Number:
WIPO Patent Application WO/2022/145508
Kind Code:
A1
Abstract:
A dual mode ROIC for MI sensor is provided. The ROIC according to an embodiment of the present invention comprises: a first detector for detecting the intensity of a magnetic field in a first manner from the output of a magnetic sensor; a second detector for detecting the intensity of the magnetic field in a second manner from the output of the magnetic sensor; and a selector for selectively activating one of the first detector and the second detector. Accordingly, both targets of improving the sensitivity/resolution of the MI sensor and power saving, which are in a trade-off relationship, can be pursued in the best way.
