Abstract
Wireless circuitry can include a radio-frequency amplifier, a power detection circuit coupled to an output of the radio-frequency amplifier and configured to output a power detection voltage, protection circuitry coupled to the power detection circuit and configured to output a protection voltage, and a control circuit configured to adjust the amplifier based on the power detection voltage and the protection voltage. The protection circuitry can include a current mirroring circuit that outputs a current proportional to a supply current of the power detection circuit and an adjustable current-to-voltage converter such as an adjustable resistor that receives the current to generate the protection voltage. The control circuit can adjust the radio-frequency amplifier by tuning a supply voltage or a bias voltage of the radio-frequency amplifier to reduce the gain of the radio-frequency amplifier, thereby proactively preventing the amplifier from outputting signals with large swings that can potentially damage the wireless circuitry.
