Abstract:
According to one aspect, embodiments of the invention provide a wireless device comprising an overstress indicator circuit including a sense circuit configured to monitor a parameter of the wireless device and generate a sense signal corresponding to the parameter, a detection circuit configured to receive the sense signal from the sense circuit and generate a detection signal in response to a determination that the sense signal is indicative of an overstress condition in the device, an interface circuit, and a memory circuit coupled to the detection circuit and the interface circuit and configured to store an overstress condition indication for access via the interface circuit in response to receiving the detection signal, at least one power amplifier coupled to the interface circuit, and a transceiver coupled to the at least one power amplifier and configured to produce an RF transmit signal and to receive an RF receive signal.
