  • Systems and methods for capacitive touch detection
    Patent number: 9841855
    Abstract: System and methods are provided for touch detection. The system includes: a sensing capacitive network configured to generate a touch-sensing signal based at least in part on a touch panel capacitance; an internal capacitive network configured to generate an input signal based at least in part on a predetermined internal capacitance; a comparative network configured to compare the touch-sensing signal with a reference signal to generate a first comparison result and compare the input signal with the reference signal to generate a second comparison result; and a signal processing component configured to generate a detection result to indicate whether a touch event occurs on the touch panel based at least in part on the first comparison result and the second comparison result.
    Type: Grant
    Filed: April 24, 2015
    Date of Patent: December 12, 2017
    Assignee: MARVELL WORLD TRADE LTD.
