METHOD OF UTILIZING DUAL COMPARATORS TO FACILITATE PRECISION SIGNAL RECTIFICATION AND TIMING SYSTEM WITHOUT SIGNAL FEEDBACK

摘要

PROBLEM TO BE SOLVED: To provide a method and an associated apparatus for a signal rectification and timing circuit.;SOLUTION: A variable amplitude input signal 12 is generated. An upper threshold level is determined and a lower threshold level is determined. The variable amplitude input signal and the upper threshold level are input into a first comparator 22. The variable amplitude input signal and the lower threshold level are input into a second comparator 42. A first digital output signal 23 is generated in the first comparator using a hysteresis circuit and a second digital output signal 43 is generated in the second comparator using a hysteresis circuit. The first digital output signal and the second digital output signal are input into a logic array 64. A digital level pulse output signal 70 that has a digital transition where the variable amplitude input signal passed through a threshold level is generated in the logic array.;COPYRIGHT: (C)2013,JPO&INPIT
