This abstract first appeared for US patent application 20250088149 titled 'Radio-frequency Amplifier with Reliability Protection
Original Abstract Submitted
wireless circuitry is provided that includes a radio-frequency amplifier, one or more power supply switches coupled to a power supply terminal of the radio-frequency amplifier, a voltage sensor or power detector coupled to the radio-frequency amplifier and configured to generate a sensor output signal, and a control logic configured to generate a digital control signal for selectively activating and deactivating the power supply switches based on the sensor output signal. a filter or adjustable latency/delay circuit can be coupled between the voltage sensor and the control logic. the filter or adjustable latency/delay circuit can have a bandwidth or latency/delay that is tuned by the control logic.
