Abstract

PURPOSE: To prevent relative fluctuation of the initial phase at the time of starting oscillation caused by the oscillating frequency when an oscillator starts oscillation from a osoillation-stopping state, by providing a constant-voltage circuit composed of plural transistors, etc.
CONSTITUTION: A constant-voltage circuit 25 is composed of transistors (Tr) 7 and 9, resistances 14, 15, and 16, and a current source 19, and the base of the Tr 7 is connected with the emitter of the Tr 9 and resistance 15. The emitter of the Tr 7 is connected with resistances 10, 11, and 14 and the resistance 14 is connected with an earth 26. The resistance 15 is connected with a power supply terminal 1. In such way, the emitter of the Tr 7 is commonly connected with the collector load resistances 10 and 11 of two Trs 4 and 5 for oscillation and fixed voltages, whose values are determined by subtracting the amounts equal to the voltage drops produced at the resistances 10 and 11 at the time of oscillation are supplied from the circuit 26 as the collector voltages of the Trs 4 and 5. Therefore, the emitter voltages of the Trs 4 and 5 at the time of oscillation-stopping state and at the peak of the oscillating state have no relation with the voltage drops produced at the resistances 10 and 11, and thus, stable voltage control can be realized. 23: input terminal 24, 25: output terminal.
