RF power detector
Last updated:
Abstract:
An RF power detector controls an amplitude of a replica input signal so that a power of the replica input signal substantially equals a power of an input signal to the RF power detector. A signal generator generates the replica input signal responsive to a digital control word. A feedback circuit adjusts the digital control word responsive to a comparison of output signals from an analog power sensor.
