This article describes a peak detector for reliable detection of small peaks in electrical signals. Detecting the peak of a voltage pulse becomes increasingly difficult as the pulsewidth decreases. If the amplitude of the pulse is also small, the problem becomes even more difficult. Because of the short charging time involved in conventional peak detectors, holding the peak voltage for a relatively long time period can also be of concern. The described design offers a practical solution with precise measurement capabilities.
