1 Abstract

An integrated circuit in which the Hall-Effect device and the sensing circuit can be incorporated on a single monolithic chip includes a Hall-Effect generator responsive to a magnetic flux change for generating a Hall-Effect voltage. A differential amplifier and current mirror circuit are coupled to the Hall-Effect device in order to vary or track the threshold voltage of the differential amplifier circuit in accordance with the output voltage from the Hall-Effect device irrespective of current changes in the Hall-Effect device due to temperature variations.
