Title (EN) MIXED-SIGNAL FULL-WAVE PRECISION RECTIFIER
(FR) REDRESSEUR PLEINE-ONDE DE PRÉCISION À SIGNAL MIXTE
Abstract:
(EN) A full-wave rectifier circuit (200) includes a comparator (220) configured to output a logic 1 or logic 0 by comparing an analog input signal to a reference voltage. The circuit further includes an analog switch (230) with a control input coupled to the comparator output. A first input of the analog switch (230) is coupled to the analog electrical input and a second input of the analog switch (230) is coupled to a reference input voltage. The switch (230) thus selects the input signal or the reference signal to output based on the comparator output. An amplifier (250) is coupled to receive the analog switch output and generate a signal following the input in an inverting or a non-inverting mode depending on the selected analog switch output, thereby generating a rectified full-wave output of the analog input signal.
(FR) Un circuit redresseur pleine-onde (200) comprend un comparateur (220) configuré pour délivrer en sortie une logique 1 ou une logique 0 par comparaison d'un signal d'entrée analogique à une tension de référence. Le circuit comprend en outre un commutateur analogique (230) doté d'une entrée de commande couplée à la sortie du comparateur. Une première entrée du commutateur analogique (230) est couplée à l'entrée électrique analogique et une seconde entrée du commutateur analogique (230) est couplée à une tension d'entrée de référence. Le commutateur (230) sélectionne ainsi le signal d'entrée ou le signal de référence à délivrer sur la base de la sortie du comparateur. Un amplificateur (250) est couplé pour recevoir la sortie de commutateur analogique et générer un signal suivant l'entrée dans un mode d'inversion ou de non-inversion en fonction de la sortie de commutateur analogique sélectionnée, générant ainsi une sortie pleine-onde redressée du signal d'entrée analogique.
