Description
| - Není k dispozici (cs)
- Sensors based on the giant magnetoresistance (GMR) effect have been used for years as the reading heads in the hard-disk technology. However, just a simple on/off detection function has been required in that application. Various techniques have been developed to make the GMRs suitable for a linear measurement of a magnetic field. Using a proper technique, we can achieve an alternating output signal of the sensor, that can be convenient for further signal processing. This paper deals with the method of alternating sensitive-axis field biasing and its influence on the sensor properties. We show that a squarewave biasing is preferred over the sinewave one, as it results in a higher sensor sensitivity and lower noise. With optimized reading circuits, we achieved a sensitivity of 20 mV/V/kA/m,a hysteresis of 0.5% in the ± 300 A/m range and a noise PSD value of 30 mA/m RMS/sqrt(Hz) at 1 Hz.
