Abstract: This invention compensates for the unintentional magnetic coupling between a first and second inductor of two different closely spaced inductors separated by a conversion circuit. A cancellation circuit formed from transistors senses the magnetic coupling in the first inductor and feeds a current opposite to the induced magnetic coupling captured by the second inductor such that the coupled magnetic coupling can be compensated and allows the first and second inductors to behave independently with regards to the coupled magnetic coupling between the first and second inductors. This allows the distance between the first and second inductors to be minimized which saves silicon area. In addition, the performance is improved since the overall capacitance in both circuits can be decreased. This cancellation technique to reduce the magnetic coupling between two closed placed inductively loaded circuits allows the design of a more compact and faster performing circuit.
