abstract = "The possibility of increasing the sensitivity of magnetoimpedance (metal) magnetic field sensors by including a high-frequency resonant circuit is considered. Various schemes of resonant circuits are presented, allowing one to increase the sensitivity of a metal magnetoimpedance sensor at a frequency of 75 MHz. The best results were obtained for a Q multiplication circuit that increases the transmission coefficient of the sensor from the external magnetic field strength from 31 to 132%/Oe with a narrowing of the bandwidth to 2.5 MHz, which results in an increase of the signal-to-noise ratio by an order of magnitude. This approach using quadrature demodulation of the signal makes it possible to distinguish signals of an alternating magnetic field with an amplitude of 1 nT with a signal-to-noise ratio of 10 dB. The proposed method can be applied for magnetoimpedance and magnetoresistive magnetic field sensors as well as for metal strain gauges during highly sensitive measurements.",

Various schemes of resonant circuits are presented, allowing one to increase the sensitivity of a metal magnetoimpedance sensor at a frequency of 75 MHz. The best results were obtained for a Q multiplication circuit that increases the transmission coefficient of the sensor from the external magnetic field strength from 31 to 132%/Oe with a narrowing of the bandwidth to 2.5 MHz, which results in an increase of the signal-to-noise ratio by an order of magnitude. This approach using quadrature demodulation of the signal makes it possible to distinguish signals of an alternating magnetic field with an amplitude of 1 nT with a signal-to-noise ratio of 10 dB. The proposed method can be applied for magnetoimpedance and magnetoresistive magnetic field sensors as well as for metal strain gauges during highly sensitive measurements.
