Abstract
Sensor devices, systems and methods are provided, including a sensor package, a first magnetic sensor, disposed within the sensor package, and configured to measure a first magnetic field in a first frequency range and output a first sensor signal based on the measured first magnetic field, a second magnetic sensor, disposed external to the sensor package, and configured to measure a second magnetic field in a second frequency range comprising frequencies higher than frequencies of the first frequency range and output a second sensor signal based on the measured second magnetic field, and a sensor circuit, disposed within the sensor package, and configured to receive the first and the second sensor signals, combine the first and the second sensor signals, and output a combined sensor signal. The first magnetic sensor and the second magnetic sensor are configured to share a cross-over frequency.
