Abstract
A circuit for detecting motion of an object includes a semiconductor substrate having first and second opposing surfaces. The circuit also includes a magnetic field sensor disposed on the first surface of the substrate and configured to generate a respective plurality of magnetic field sensor output signals in response to a magnetic field associated with the object. At least one of the magnetic field sensor output signals is indicative of an angular position of the magnetic field with respect to the sensor. Additionally, at least one of the magnetic field sensor output signals is indicative of an amplitude of the magnetic field.
