Original Abstract Submitted
Wireless circuitry can include a radio-frequency amplifier and a power detection circuit coupled to an output of the radio-frequency amplifier. The power detection circuit can include an input transistor, a biasing circuit configured to output a bias voltage for the input transistor and configured to track temperature and voltage variations, and a non-linearity cancellation component configured to generate a current that at least partially cancels a non-linear current associated with the input transistor. The input transistor may be an n-type transistor, and the non-linearity cancellation component may be a p-type metal-oxide-semiconductor capacitor. The biasing circuit can include n-type and p-type diode-connected bias transistors.
