Abstract
A peak detector provides repeatable and accurate measurements of the signal amplitude for variable frequencies of input signals. The peak detector includes a pulse edge generator circuit that generates a pulse edge signal in response to the signal peaks of an input signal and a sampler circuit that is triggered to sample the input signal by the pulse edge signal. The pulse edge generator circuit compares the input signal with a delayed version of the input signal to produce a differential signal and generates the pulse edge signal using the differential signal. An analog or digital sampler is triggered by the pulsed edge signal to measure the information, e.g., peak value, of the input signal. One or more delay circuits may be used to align the edges of the pulsed edge signal with the peaks of the input signal.
