In accordance with an embodiment, a drive circuit is provided for driving for a motor wherein the drive circuit includes a first signal generator coupled to a second signal generator. A bias generator is connected to the second signal generator. In accordance with another embodiment, a method for driving a motor is provided that includes comparing a first signal at a first output of a Hall sensor with a second signal at a second output of the Hall sensor to generate a comparison signal. An indicator signal is generated in response to the comparison signal, wherein the indicator signal has a first edge and a second edge. A bias signal for the Hall sensor is generated in response to the indicator signal in response to the indicator signal.
