1. A converter for converting a voltage into time, the converter comprising:
a direct path comprising a first injection-locked oscillator and a first circuit, the first circuit being configured for receiving an output signal of the first oscillator and a reference signal, and for providing at least a first pulse signal determined by a phase shift between the output signal of the first oscillator and the reference signal; and
a feedback loop comprising a second circuit configured for integrating said at least one first pulse signal,
wherein the first oscillator is configured for being controlled by a difference between the voltage to be converted and an output voltage of the feedback loop, the output voltage of the feedback loop being determined by an output voltage of the second circuit representative of the integration of said at least one first pulse signal, the feedback loop and the direct path being configured so that a loopback of the feedback loop on the direct path implements a negative feedback.
