Circuit principle: 1) A leading edge current-threshold provides a timing pickoff from the input single pulse; 2) The charge of the input pulse is integrated between the two thresholds at the rise and fall pulse edges. 3) At the end of a peak holding with predefined time period TD, a discharge starts at a timing t2 and terminates at t3 determined by a voltage threshold.
