Abstract: An electronic circuit comprises at least one radiation-emitting element (2), a current regulator (12) with a current-producing terminal (O), and a measurement element (14) generating a signal (Vmes) that is representative of the current flowing therethrough. A switch (6) is controlled by a modulation signal (M) so as to open and close, successively, an electrical path passing through the current-producing terminal (O), the radiation-emitting element (2) and the measurement element (14). A conversion circuit (16) is further interposed between the measurement element (14) and the current regulator (12) so as to transform the representative signal (Vmes) into a smoothed signal (S) that is intended for a regulation terminal (Reg). A time-of-flight sensor comprising such an electronic circuit is also provided.
