Title (EN) ELECTRONIC CIRCUIT AND TIME-OF-FLIGHT SENSOR COMPRISING SUCH AN ELECTRONIC CIRCUIT
(FR) CIRCUIT ÉLECTRONIQUE ET CAPTEUR DE TEMPS DE VOL COMPRENANT UN TEL CIRCUIT ÉLECTRONIQUE
Abstract:
(EN) 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.
(FR) Un circuit électronique comprend au moins un élément émetteur de rayonnement (2), un régulateur de courant (12) avec une borne de production de courant (O), et un élément de mesure (14) produisant un signal (Vmes) représentatif du courant le traversant. Un interrupteur (6) est commandé par un signal de modulation (M) de manière à successivement ouvrir et fermer un chemin électrique passant par la borne de production de courant (O), l'élément émetteur de rayonnement (2) et l'élément de mesure (14). Un circuit de conversion (16) est par ailleurs interposé entre l'élément de mesure (14) et le régulateur de courant (12) de manière à transformer le signal représentatif (Vmes) en un signal lissé (S) destiné à une borne de régulation (Reg). Un capteur de temps de vol comprenant un tel circuit électronique est également proposé.
