Patent number: 11799436Abstract: A method of forming a resonator includes forming top and bottom dielectric structures over a substrate. A piezoelectric layer is formed between the top and bottom dielectric structures. A bottom electrode is formed between the piezoelectric layer and the bottom dielectric structure, and a top electrode is formed between the piezoelectric layer and the top dielectric structure. A metal layer is formed over the top dielectric structure and is patterned, thereby forming a first contact pad making electrical contact to the top electrode, a second contact pad making electrical contact with the bottom electrode, and a mass bias located over the top dielectric structure.Type: GrantFiled: August 27, 2019Date of Patent: October 24, 2023Assignee: Texas Instruments IncorporatedInventors: Byron Neville Burgess, William Robert Krenik, Stuart M.

Patent number: 11265009Abstract: A circuit includes a phase-locked loop having a phase-locked loop output to provide a first phase signal and a second phase signal phase delayed with respect to the first phase signal. The circuit further includes a digital circuit having a digital circuit input and an output. The digital circuit input couples to the phase-locked loop output. On the digital circuit output, the digital circuit is configured to provide a first digital-to-analog converter (DAC) enable signal and a second DAC enable signal. The circuit also includes first and second DACs. The first DAC is coupled to the digital circuit. The first DAC has a first enable input coupled to the digital circuit output to receive the first DAC enable signal. The second DAC is coupled to the digital circuit. The second DAC has a second enable input coupled to the digital circuit output to receive the second DAC enable signal.Type: GrantFiled: December 30, 2019Date of Patent: March 1, 2022Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Keliu Shu, Gary Franklin Chard, William Robert Krenik

Publication number: 20190187854Abstract: A system includes a receiver that receives an output signal from a touch system to detect a user's touch. The output signal is received in response to an excitation signal that is applied to a row or column of the touch system. A touch force analyzer determines an indication of a touch force applied to the touch system based on detecting a change in phase of the output signal received from the row or column of the touch system in response to a touch applied to the touch system.Type: ApplicationFiled: December 15, 2017Publication date: June 20, 2019Inventors: SRINATH HOSUR, ASHISH KHANDELWAL, WILLIAM ROBERT KRENIK
