Abstract
Techniques are described for magnetic field detection using a plurality of Hall sensors and chopper-amplifier circuit. Determination that a magnetic field is present from measurement from one of the Hall sensors may trigger confirmation or confirmation and reconfirmation of the presence of the magnetic field from measurements from one or more of the other Hall sensors.
