  • System and method for mutual capacitance sensing
    Patent number: 10635228
    Abstract: A display device includes: a display panel configured to display an image at an active area; a touch screen panel overlapping the display panel at the active area, the touch screen panel comprising an input line and an output line; and an operational amplifier having an input electrode coupled to the input line and an output electrode coupled to the output line, wherein the display device is configured to measure a voltage at the output electrode of the operational amplifier for detecting a touch event at an intersection between the input line and the output line.
    Type: Grant

  • Second order switched capacitor filter
    Patent number: 10153751
    Abstract: A switched capacitor low-pass filter. The filter includes a plurality of switched capacitors, and a plurality of resistors. The resistors increase the slope of the roll-off of the filter, reduce DC gain variations across corners, and minimize the frequency variation across corners. In some embodiments, the clock signal used to control the switched capacitor filters has a duty cycle differing from 50%, to improve the frequency response of the filter.
