  • Differential-difference-amplifier-based touch sensor interface
    Patent number: 12141396
    Abstract: Techniques are described for touch event sensing in a capacitive touch panel that is integrated with a display. In some such environments, a large amount of display noise is capacitively coupled with the touch sensing signals. This can degrade performance of conventional sensing approaches, which tend to use a buffering stage followed by a difference amplifier stage. Embodiments provide a single-stage, differential-difference-amplifier-based touch event sensing approach that pre-cancels coupled display noise from adjacent channels by common-mode rejection prior to amplifying, thereby generating amplified differential output signals that include substantially only the desired touch sensing information.
