Abstract
Examples herein provide multi-turn coil multiplex circuits. The multi-turn coil multiplex circuits include a multi-turn coil, a switch, a near field communication (NFC) matching circuit, and a camera circuit. The switch includes a common port, a first port, and a second port. The multi-turn coil is connected to the common port. The NFC matching circuit is connected to the first port. The camera circuit is connected to the second port. Where a camera control signal is present, the connection with the second port is activated and the multi-turn coil can be used as a camera focusing coil associated with the camera circuit. Where no camera control signal is present, the connection with the first port is activated and the multi-turn coil can be used as an NFC antenna associated with the NFC matching circuit.
