Claim Text:
1. A spinning Hall sensor comprising: a Hall sensing element with terminals; wherein the spinning Hall sensor is configured to apply bias signals in a first spin sequence to a first sequence of terminal configurations of the Hall sensing element, the terminals of the Hall sensing element interconnected in the first sequence of the terminal configurations between a bias supply and ground, with the bias supply being connected to and applying the bias signal in each terminal configuration of the first sequence to a different one of the terminals; and wherein the spinning Hall sensor is configured to apply bias signals in a second spin sequence to a second sequence of the terminal configurations, the terminals of the Hall sensing element interconnected in the second sequence of the terminal configurations between the bias supply and the ground, with the bias supply being connected to and applying the bias signal in each terminal configuration of the second sequence to a different one of the terminals, wherein the bias signals applied in the second spin sequence are inverted from the bias signals applied in the first spin sequence; and wherein the spinning Hall sensor is configured to provide an output signal based on first signals obtained from Hall sensing measurements in the first spin sequence and second signals obtained from Hall sensing measurements in the second spin sequence.
