Abstract

The oscillator circuit comprises an active amplifier transistor 1 which is supplied by a current source comprising a second active amplifier transistor 13 whose control electrode 13a is connected to the control electrode 1b of the first transistor by way of capacitive decoupling means 22, 23. The first and second transistors 1, 13 are of opposite conductivity types. Bias circuits 4, 14 apply to the control electrode of the second transistor a control signal 13a which contains the oscillation signal VA which is superimposed on a d.c. voltage which depends on the amplitude of the oscillation signal. This circuit can be used in particular for the time bases of electronic watches. <IMAGE>
