Abstract: A circuit includes a radio frequency (RF) detector having an RF detector input and an RF detector output. The RF detector is configured to provide a first signal at the RF detector output responsive to a second signal at the RF detector input. The circuit further includes a processing circuit having a processing terminal coupled to the RF detector output. The processing circuit is configured to provide a third signal at the terminal based on scaling the first signal by a factor that is proportional to temperature.
