Injection-locked oscillator with variable load impedance

An injection-locked oscillator comprising at least:

• one or several control inputs configured to receive one or several control signals, the oscillator being configured such that the value of its natural frequency depends on the amplitude of the control signal(s);
• a synchronisation input configured to receive a periodic synchronisation signal, the oscillator being configured to output an output signal with a frequency equal to the frequency of the synchronisation signal when the oscillator is locked to the frequency of the synchronisation signal, and such that a phase shift between the output signal and the synchronisation signal depends on a difference between the natural frequency of the oscillator and the frequency of the synchronisation signal;
• a first load impedance, the oscillator being configured such that a load signal is applied on the first load impedance;
• a second load impedance;
• a first coupling component configured to periodically couple the second load impedance to the first load impedance, at the frequency of the synchronisation signal, in parallel or in series,
• wherein each of the first and second load impedance comprises at least one of:
• a capacitor, a capacitive component, a coil, and an inductive component.
