Method and apparatus of cancelling inductor coupling

An apparatus comprising:

• a source circuit coupled to a power supply by at least one inductor;
• a conversion circuit coupled to said power supply by at least one other inductor;
• a magnetic coupling between said one inductor and said other inductor;
• a cancellation circuit responsive to at least one output signal from said source circuit;
• said cancellation circuit coupled to said other inductor to compensate for said magnetic coupling;
• and
• a current output of said cancellation circuit introduced into said other inductor that cancels said magnetic coupling between said one inductor and said other inductor.

A method of compensating for a magnetic coupling comprising the steps of:

• generating signals from a quadrature oscillator coupled to a power supply by two or more inductors;
• coupling a conversion circuit to said power supply by another two or more inductors;
• magnetically coupling said two or more inductors to said another two or more inductors;
• applying, said signals from said quadrature oscillator to a cancellation circuit;
• compensating for said magnetic coupling by coupling a differential current of said cancellation circuit to said another two or more inductors;
• mixing differential baseband signals with said signals from said quadrature oscillator;
• and summing said mixed differential baseband signals.
