Apparatus and method using a plurality of magnetic field sensitive devices coupled such that multiple currents flow through at least one of the magnetic field sensitive devices

A method for detecting a magnetic field using an apparatus comprising a plurality of magnetic field sensitive devices each having at least three terminals and grouped into N groups, with N>1, wherein k and N are natural numbers and k is an index for a respective group from 1 to N, wherein each group k comprises 2k-1 magnetic field sensitive devices, for 1≤k≤N, wherein the plurality of magnetic field sensitive devices are coupled such that, for 1<k≤N, supply currents flowing through two magnetic field sensitive devices in group k flow through one magnetic field sensitive device in group k-1, the method comprising:

• providing a supply current independently through each magnetic field sensitive device of group N;
• tapping an output signal at at least one contact of at least one magnetic field sensitive device of each group k of the N groups;
• and
• combining each tapped output signal into an overall output signal representing a measurement of the magnetic field.
