In this paper, a low-frequency parametric magnetic sensor with a magnetic ribbon and the Antoniou general impedance converter is described. A low-frequency parametric magnetic sensor with the parametric oscillation frequency of about 20 kHz is examined. We show that the sensor has the sensitivity of 1.04 mVp-p/(A/m) without any amplifier and detects the constant output voltage independent of the frequency band from 1 Hz to 1 kHz.
