An autogenerator induction-to-frequency converter circuit based on a field-effect Hall sensor with a regulated frequency

Autogenerator magnetic field converter circuits based on a field-effect Hall sensor (FEHS), are considered. The feasibility of creating microelectronic high-sensitive magnetic-field sensors with a frequency output and regulated operating frequency is shown. A FEHS-based induction-to-frequency magnetic field converter circuit is tested. The converter sensitivity is 100−600 Hz/mT, the stability of the operating frequency of the autogenerator is 1%, and the operating frequency can be controlled by changing potentials of the FEHS gates in the range of 6−20 kHz.
