Programmable voltage to time converter

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.
