Patent number: 10532923Abstract: Methods and apparatus for reducing the oscillation of a MEMS actuator. In one embodiment, a driving signal is generated to adjust the MEMS actuator through a set of driving wires coupled to the MEMS actuator. A motion-induced signal from the set of driving wires coupled to the MEMS actuator is received in response to the driving signal. The motion-induced signal is filtered to generate a filtered motion-induced signal. The filtered motion-induced signal is amplified to generate an amplified filtered motion-induced signal. The driving signal is adjusted based on the amplified filtered motion-induced signal to reduce the oscillation of the MEMS actuator.Type: GrantFiled: February 14, 2018Date of Patent: January 14, 2020Assignee: Futurewei Technologies, Inc.Inventors: Jianmin Gong, Francis Man, Dongyu Geng, Xin Tu, Ming Li, Jiejiang Xing, Yusheng Bai
