Patent number: 11172312Abstract: The present disclosure relates generally to a microphone assembly. The microphone assembly has an acoustic activity detection mode of operation when the electrical circuit is clocked using an internal clock signal generator in the absence of an external clock signal at a host interface, and an electrical circuit of the microphone assembly is configured to provide an interrupt signal to the host interface upon detection of acoustic activity by the electrical circuit. The electrical circuit is configured to control the operating mode of the microphone assembly based on a frequency of the external clock signal in response to providing the interrupt signal and is configured to provide data representing the electrical signal to the host interface using the external clock signal received at the host interface.Type: GrantFiled: January 26, 2020Date of Patent: November 9, 2021Assignee: Knowles Electronics, LLCInventors: Claus Erdmann Fürst, Henrik Thomsen, Michael Deruginsky, Dibyendu Nandy, Oddy Nopporn Khamharn, Aziz Yurttas, Svetoslav Radoslavov Gueorguiev, Anders Mortensen

Patent number: 10028054Abstract: An application specific integrated circuit (ASIC) is used with an acoustic device. An input clock signal is received. The frequency of the input clock signal is determined, and the frequency is indicative of one of a plurality of operational modes of the ASIC. Based upon the determined frequency, an amount current provided to one or more operational blocks of the ASIC is changed.Type: GrantFiled: October 13, 2014Date of Patent: July 17, 2018Assignee: Knowles Electronics, LLCInventors: Claus Erdmann Furst, Aziz Yurttas, Svetslav Gueorguiev, Anders Mortensen

Patent number: 9668051Abstract: A driver, includes a driver block, a controller block, and a comparison block. The driver block includes an adjustable current source configured to produce a digital output stream. The controller block is coupled to the driver block. The comparison block is coupled to the driver block and the controller block. The comparison block is configured to compare the digital output stream to a reference value at a time delayed with respect to a master clock and based upon the comparison cause the controller block to adjust a strength of the driver block.Type: GrantFiled: June 23, 2016Date of Patent: May 30, 2017Assignee: Knowles Electronics, LLCInventors: John Nielsen, Claus Erdmann Furst, Aziz Yurttas, Anders Svava Mortensen, Paul Smith

Publication number: 20140197887Abstract: An operational amplifier includes a transfer circuit, a cascode control circuit, and a slew rate boost circuit. The transfer circuit is configured to apply a transfer function to a received input signal and the application of the transfer function to the received input signal is effective to create an output signal. The cascode circuit is coupled to the transfer circuit. The cascode circuit is configured to increase an open loop gain of the operational amplifier. The slew rate boost circuit is coupled to the cascode circuit. The slew rate boost circuit is configured to increase the slew rate of the operational amplifier without necessarily increasing the power consumption of the operational amplifier.Type: ApplicationFiled: January 14, 2014Publication date: July 17, 2014Applicant: Knowles Electronics, LLCInventors: Per Flemming Hovesten, Claus Erdmann Furst, Aziz Yurttas
