A switchable voltage-controlled oscillator at least including : at least one signal input node receiving reference and modulation signal inputs; a signal output node; a resonant circuitry establishing the operating frequency range of the voltage-controlled oscillator and being coupled to the at least one signal input node; an amplifier having an input coupled to the resonant circuitry and an output coupled to the signal output node; a feedback path extending from the output of the amplifier to the resonant circuitry; the resonant circuitry being switchable to introduce at least one reactive circuit element thereto to alter the operating frequency range of the voltage-controlled oscillator.
