Abstract:
A driver for a circuit with a capacitive load, includes a power converter configured to receive a DC input voltage from an input stage, generate a switching voltage at a switching node, and output an output voltage forming an analog waveform at an output stage. The power converter includes a first switch connected between an inductive device and a ground, a second switch connected between the inductive device and the output stage, and a controller to control the first switch and the second switch. The analog waveform has an amplitude at least two times greater than the input voltage.
