Abstract
A circuit for resolving a magnetic field, including a first channel including a first magnetic field sensor, a first amplifier coupled to and receiving an output from said first magnetic field sensor, and a first three band detector coupled to and receiving an output from said first amplifier. The first three band detector provides a first two bit output. A second channel includes a second magnetic field sensor, a second amplifier coupled to and receiving an output from said second magnetic field sensor, and a second three band detector coupled to and receiving an output from said second amplifier. The second three band detector provides a second two bit output. The first and second magnetic field sensors are arranged orthogonally to one another such that said first and second two bit outputs resolve the magnetic field into eight bearings.
