Patent number: 9712923Abstract: A microphone includes a microelectromechanical system (MEMS) circuit and an integrated circuit. The MEMS circuit is configured to convert a voice signal into an electrical signal, and the integrated circuit is coupled to the MEMS circuit and is configured to receive the electrical signal. The integrated circuit and the MEMS circuit receive a clock signal from an external host. The clock signal is effective to cause the MEMS circuit and integrated circuit to operate in full system operation mode during a first time period and in a voice activity mode of operation during a second time period. The voice activity mode has a first power consumption and the full system operation mode has a second power consumption. The first power consumption is less than the second power consumption. The integrated circuit is configured to generate an interrupt upon the detection of voice activity, and send the interrupt to the host.Type: GrantFiled: May 20, 2014Date of Patent: July 18, 2017Assignee: Knowles Electronics, LLCInventors: Claus Erdmann Fürst, Henrik Thomsen, Michael Deruginsky, Dibyendu Nandy, Oddy Nopporn Khamharn
