Abstract
A driver for a circuit with a capacitive load, is disclosed, including an input stage, a bi-directional power converter, and a controller to control the driver. The power converter includes an inductive device and two switches configured to receive a DC input voltage vfrom the input stage and generate an analog output waveform having an amplitude greater than vproviding an output distortion below 5% without an output low-pass filter.
