ERROR REMOVING AMPLIFIER CIRCUIT

摘要

To provide an error removing amplifier circuit which reduces distortion in a Hall detection signal.SOLUTION: An error removing amplifier circuit comprises: an amplifier module; a switch module which is electrically connected to an output terminal of the amplifier module; a comparator module which includes a first comparator and a second comparator; an output comparator; and an adjustment module which is electrically connected to the amplifier module. In the error removing amplifier circuit, the amount of deviation in at least one Hall detection signal is removed by the amplifier module, the switch module, and the adjustment module. The output comparator is configured such that a first input terminal is electrically connected to a signal output terminal of the amplifier module and a second input terminal is electrically connected to a reference voltage.SELECTED DRAWING: Figure 1
