Original Abstract Submitted
radio frequency (rf) transmitters of a device (aggressor device) may unintentionally transmit a high-power output signal to antennas of a receiving device (victim device). in some rf systems, a victim device may have no or little protection between its antennas and transistors in an integrated circuit. performance or lifetime of the transistors may be negatively impacted due to large voltage swings that may result from the high-power signal received from the aggressor device. to prevent or mitigate impact to performance or lifetime of the transistors due to the large voltage swings, protection circuitry including switches and a direct current (dc) power source (e.g., a charge pump) may be implemented at an input of a receiver of the victim device to shunt the power from sensitive circuit components of the victim device.
