Abstract
A frequency/voltage conversion circuit is provided with a detection circuit for determining when the input frequency rises above a predetermined level which threatens to inhibit operation of flip-flop devices in the circuit. In response to the detection, a capacitor of a first charging/discharging circuit is forcibly charged to a value above a predetermined level.
