Abstract
A detector circuit includes a main path having a first detector to generate an output signal in response to an input signal, and a reference path having a second detector matched to the first detector to generate a reference signal in response to the input signal. The reference signal may be used to compensate the output signal for variations in operating frequency, temperature, or the like. The reference path may be arranged to reuse a signal available in the main path so that the signal applied to the second detector experiences the same operating effects as that applied to the first detector.
