Abstract
A switching circuit comprises a first transistor, a transformer including a first inductor and a second inductor that is co-centric with the first inductor, a first switch, a second switch, a second transistor, a first output, a second output, and coupling circuitry configured to couple the first inductor to the first transistor, a first end of the second inductor, the first switch, and the first output together at a first node, a second end of the second inductor, the second switch, and the second transistor together at a second node, and the second output to the second transistor.
