Abstract: An antenna tuning circuit achieves robust performance in a closed loop antenna tuning system due to the addition of protection circuits. In one instance, a protection circuit to detect an overload condition based on a threshold value may be included in the antenna tuning circuit. The antenna tuning circuit also includes a protection state register coupled to the protection circuit to store one or more safe states of operation to which the circuit is restored in response to detecting the overload condition. The antenna tuning circuit also includes a bus interface coupled to the protection state register to transmit an indication of a state of operation of the circuit to an external tuning control device coupled to the circuit and to receive pre-defined protection actions from the external tuning control device in response to the indication of the state of operation.
