Abstract

The invention concerns a programmable voltage to time converter (10), comprising:- a locking frequency generator (12) configured to generate a locking frequency;- a current generator (14) configured to generate a biasing current;- a relaxation oscillator (18) 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 (20) 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 (18) comprises a component presenting a linearly controllable characteristic. The voltage to time converter (10) presents a gain linearly or dB-linearly controllable based on the gain control word by controlling linearly said characteristic of said component.
