Abstract
A circuit for driving a capacitive load includes an amplifier for driving the load based on an input signal, the amplifier comprising at least a boost converter, a dynamic model configured to track a capacitance of the load and a voltage of the source for powering at least parts of the circuit, an adaptive filter, configured to filter the input signal based on an output of the dynamic model.
