PEAK-TO-PEAK SIGNAL DETECTOR

摘要

A detector (14) to determine the peak-to-peak value of a signal (18) is presented. The detector (14) includes a first circuit (26) to provide a tracking signal that tracks a positive slope of the signal (18) during a first time interval and a negative slope of the signal during a second time interval. The detector further includes a second circuit (20) configured to produce values associated with the tracking signal provided during one of the first and second time intervals, where one of the values is indicative of the peak-to-peak value (20) of the signal (18).
