Claim:
1. A method for configuring a circuit, the method comprising: determining whether the circuit is to be transitioned from a state for receiving a magnetic field to a state for creating the magnetic field, wherein, in the state for receiving the magnetic field, a first switch, a second switch, and a third switch are open and a fourth switch and a fifth switch are closed; closing the first switch to couple a predriver to a first transistor; closing the second switch to couple the predriver to a second transistor; closing the third switch to couple the predriver to a third transistor; opening the fourth switch to remove a direct connection between a voltage regulator and the second transistor; opening the fifth switch to remove a direct connection between a clamp control and the third transistor; and passing a signal from the predriver to a first port of an antenna via the first transistor, the second transistor, and the third transistor when the circuit is in the state for creating the magnetic field.
