ABSTRACT:
An in-phase voltage elimination circuit in which a Hall element has first and second control current input terminals and first and second output terminals, the first and second control current input terminals fed with a control current and the first output terminal connected to one input terminal of an operational amplifier. The other output of the operational amplifier is connected to ground, and the output terminal of the operational amplifier is connected to one of the first and second control current input terminals. A Hall output is produced at the second output terminal of the Hall element.
