Abstract
A piezo driver is described that is configured to furnish electric charge to a piezo component during a first operational state and configured to transfer electric charge from the piezo component to a passive energy storage component during a second operational state. In one or more implementations, the piezo driver includes a passive energy storage component configured to store electric charge. The piezo driver also includes a voltage converter configured to electrically connect between a piezo component and the passive energy storage component. The voltage converter is configured to furnish electric charge from the passive energy storage component to the piezo component during a first state of operation and configured to furnish electric charge from the piezo component to the passive energy storage component during a second state of operation.
