Abstract
The invention concerns an oscillator including an input terminal, an output terminal, a resonator, and an oscillator circuit including: first and second power supply terminals, two capacitors connected between the first power supply terminal and the input terminal, and respectively the output terminal of the oscillator; first and second active transistors of complementary type, forming therewith an inverting amplifier, first and second means for respectively polarizing the first and the second active transistors, a first current source formed by a transistor of the same type as the second active transistor, between the second power supply terminal and the second active transistor, current control means for the second polarizing means, characterized in that in an steady operating conditions, said second polarizing means are arranged for providing a polarization voltage across the gate of the second active transistor corresponding to the transistor gate voltage of the first current source to within one voltage shift.
