| titleOfInvention | Piezoelectric actuator drive system |
| abstract | Disclosed herein is a piezoelectric actuator drive system for forward or backward driving a piezoelectric actuator for zooming and/or focusing in a camera module. The piezoelectric actuator drive system comprises a power supply for supplying an operating voltage, a drive controller for controlling generation of a forward/backward drive signal for a piezoelectric actuator in response to an operation ON select signal and a forward/backward driving select signal, a clock generator for generating a first clock signal in response to the operating voltage from the power supply, and a drive signal generator for generating and supplying the forward or backward drive signal to the piezoelectric actuator in response to the first clock signal from the clock generator and the operating voltage from the power supply under the forward/backward drive signal generation control of the drive controller. |
