Piezoelectric motor drive circuit and method

A piezoelectric transducer is driven to mechanically oscillate a mirror at a mechanical resonant frequency with high precision despite frequency variations introduced by temperature, tolerances and ageing of components. Switches are actuated at different times in order to make the drive frequency co...
