This was intended to be a peak holding circuit with integrated, configurable reset logic. It works to an extent but has several flaws as is: - The peak hold works, but only with input pulses above threshold (some hundred or so millivolt) - The reset logic is a bit finnicky; the internal delays for processing the logic signals is not quite calibrated and could use some work.
