ABSTRACT:
A timing circuit utilizing first and second hysteresis comparators. The first comparator senses the voltage across a capacitor in a first charging circuit. Whenever this voltage exceeds the high comparator reference level, the comparator output is at a first voltage level, permitting charging of the capacitor. When the capacitor voltage drops below the low comparator reference level, the comparator output switches to a second level, discharging the capacitor at a rate much faster than the charging rate. The second comparator interacts with a second capacitor in similar fashion; however, the second capacitor is permitted to charge only during the discharge periods of the first.
