An electronic oscillator comprising:
- a resonator coupled in parallel with at least one active circuit, the resonator comprising two electrodes coupled to distinct variable capacitive elements forming a charge capacitive element of the electronic oscillator, and
- a control device configured to independently control values of the variable capacitive elements.
A control method of an electronic oscillator comprising:
- coupling a resonator in parallel with at least one active circuit, the resonator comprising two electrodes coupled to distinct variable capacitive elements forming a charge capacitive element of the electronic oscillator, and
- independently controlling, by a control device, values of the variable capacitive elements.
