Method and system for isolated coupling

A method for isolatively coupling an input signal to an output signal in an integrated circuit, the method comprising:

• providing first and second conductive plates operable to receive the input data signal;
• providing at least one magnetic sensor having a region of conductive material, the magnetic sensor operable to receive a current from a current source and to conduct the current through the region of conductive material;
• electrically connecting a plurality of conductive nodes to the conductive material, the conductive nodes operable to allow measurement of a voltage difference arising due to a magnetic field acting on the region of conductive material;
• electrically connecting a conductor at one end to the first conductive plate and electrically connecting the other end to the second conductive plate;
• positioning the conductor proximate the magnetic sensor, the conductor operable to conduct a current generated by the input signal thereby generating the magnetic field;
• receiving the input signal resulting in a first differential voltage between the first and second conductive plates;
• capacitively coupling the first differential voltage to a second differential voltage along a first parallel path to produce a first output signal representative of the input signal using a first amplifier and a first comparator;
• magnetically coupling the first differential voltage to a third differential voltage along a second parallel path to produce a second output signal representative of the input signal by measuring the voltage difference across the magnetic sensor due to the magnetic field generated by the current produced by the first voltage differential and producing a second output signal representative of the input signal using a second amplifier and a second comparator;
• and
• creating an output signal chosen from the group consisting of the first output signal and the second output signal.
