Abstract
Disclosed is a driver stage for activating a first ultrasonic transducer and a method for the operation thereof. The driver stage comprises a first charge pump or power source and a first capacitor. The driver stage also comprises first means for charging the first capacitor with electrical energy from the charge pump and second means for connecting the first capacitor and ultrasonic transducer to different polarities. The first means do not charge the first capacitor with energy from the charge pump or power source when the first capacitor is connected to the ultrasonic transducer by the second means.
