Abstract

Methods, apparatus, systems, and articles of manufacture are described corresponding to wide bandwidth hall sensing circuitry. An example circuit includes a first hall effect sensor configured to output a first voltage corresponding to a magnetic field; an amplifier to output an amplified voltage by amplifying the first voltage; a second hall effect sensor configured to output a second voltage corresponding to the magnetic field, the second hall effect sensor operating using a spinning technique to toggle a bias current between terminals of the second hall effect sensor, the spinning technique to remove a first offset corresponding to the second hall effect sensor; and offset reduction circuitry configured to: determine a second offset corresponding to the first hall effect sensor based on the first voltage and the second voltage; and generate an output based on the second offset, the amplifier to adjust the amplified voltage based on the output.
