Abstract
Apparatus and methods are provided directed to a device, including at least one ultrasonic transducer, a level shifter coupled to the at least one ultrasonic transducer, the level shifter including an input terminal configured to receive an input voltage, an output terminal configured to provide an output voltage level-shifted from the input voltage, a capacitor coupled between the input terminal and the output terminal, and a diode coupled in reverse-biased configuration between an input to an active high voltage element and a first voltage of a high voltage power supply.
