[[Optical Component]] Continuous capacitance measurement for mems-actuated movement of an optical component within an auto-focus camera module

A MEMS-actuated autofocus camera module configured for continuous capacitance measurement includes a bridge balance detector coupled to a MEMS actuator driver. The MEMS actuated autofocus camera module is configured to permit online MEMS actuator capacitance measurements to automatically focus images of objects disposed at arbitrary distances from autofocus camera module....
