Abstract
PURPOSE: To avoid the occurrence of sag, by controlling the gate with the signal controlling the operation of phase comparison, through the provision of gates between the load and the reference voltage.
CONSTITUTION: Gates Q20, Q21 are provided between the reference voltage point E0 giving a DC bias and the load resistor R1. Further, the detection output to the reference voltage is produced through the conduction of the gates Q20 and Q21 while the phase comparison. The gates are inoperative while no phase comparison is made to interrupt the discharge path flowing to the reference voltage point E0 via the load resistor R1. Accordingly, no sag is produced, allowing to avoid the unnecessary increase in the detection sensitivity.
