Abstract
A transformer has a first inductor that includes a first port. The transformer also has a second inductor magnetically coupled to the first inductor. The second inductor includes a second port. The second inductor includes a first portion configured to permit current flow in a clockwise direction and a second portion configured to permit current flow in a counter-clockwise direction. The transformer also has a third inductor magnetically coupled to the first inductor. The third inductor includes a third port. The counter-clockwise direction is opposite the clockwise direction to reduce magnetic coupling between the second inductor and the third inductor based on magnetic coupling cancellation.
