Abstract: The present disclosure relates to a converter (1) converting a voltage (Vin) into time. The converter comprises a direct path (100) including a first injection-locked oscillator (104) and a first circuit (106). The first circuit is configured for receiving an output signal (?sens) of the first oscillator and a reference signal (?0), and for providing at least a first pulse signal (out) determined by a phase shift between the output signal (?sens) of the first oscillator and the reference signal (?0). The converter further comprises a feedback loop (102) comprising a second circuit (108) configured for integrating said at least one first pulse signal (out).

Abstract: The invention concerns a programmable voltage to time converter, comprising: a locking frequency generator configured to generate a locking frequency; a current generator configured to generate a biasing current; a relaxation oscillator configured to be powered by the biasing current and to generate an output voltage signal from the locking frequency, a gain control word and an input voltage signal; a phase difference block configured to determine a phase difference between a first signal corresponding to the output voltage signal and a second signal determined based on the locking frequency. The relaxation oscillator comprises a component presenting a linearly controllable characteristic. The voltage to time converter presents a gain linearly or dB-linearly controllable based on the gain control word by controlling linearly said characteristic of said component.
