CAPACITOR TYPE TIMING CIRCUIT UTILIZING ENERGIZED VOLTAGE COMPARATOR

摘要

There is provided a strobed timing circuit which includes a timing capacitor connected across a voltage source for charging at a predetermined rate, and a comparator circuit for providing an output signal when the voltage across the capacitor reaches a set-in value. The comparator circuit is turned on for relatively short intervals of time to measure the voltage across the capacitor to thereby provide a comparator circuit with an apparently high input impedance.
