Specificity of Magnetic Measurements using the Controllable Hall Element as a Primary Magnetic Field Converter

New circuitry possibilities of magnetic measurements using the controllable field effect Hall sensor (FEHS) as a primary magnetic field converter are considered. The FHP combines the properties of the conventional Hall probe and field-effect transistor with a two-gate control system such as metal--insulator--silicon- insulator-metal. Two field control systems allow control of FEHS parameters, as well as the use of new circuitry to control the dynamic range of magnetosensitivity, operating current stability, and measurement stability improvement under conditions of variable external influences (temperature, radiation background).
