Title (EN) EFFICIENT ON-CHIP HIGH-VOLTAGE DRIVER CIRCUIT FOR ULTRASONIC TRANSDUCER
(FR) CIRCUIT D'ATTAQUE HAUTE TENSION SUR PUCE POUR TRANSDUCTEUR À ULTRASONS
Abstract: front page image
(EN)An ultrasound transducer may be driven by a driver circuit having one or more charge pumps and a multi-level inverter. The one or more charge pumps are configured to drive the ultrasound transducer only during output transitions of the inverter.
(FR)Un transducteur à ultrasons peut être attaqué par un circuit d'attaque ayant une ou plusieurs pompes de charge et un onduleur multi-niveau. Les une ou plusieurs pompes de charge sont configurées pour attaquer le transducteur à ultrasons uniquement pendant des transitions de sortie de l'onduleur.
