  • Full-bridge tip driver for active stylus
    Patent number: 9104251
    Abstract: A method and apparatus to increase a transmit (TX) signal generated by an active stylus without increasing the power consumption of the active stylus. In one aspect, the active stylus increases the amplitude of the TX signal. In another aspect, the active stylus increases the TX signal by providing the capacitance of a body of a user to the stylus.

  • Quadrature signal receiver using synchronized oscillator
    Patent number: 8493360
    Abstract: A system comprises a processing device, a signal generator to generate a first signal and a single receiver to receive a second signal from a capacitive sense array. The single receiver is configured to process the second signal for stylus sensing of a stylus proximate to the capacitive sense array in a first mode of operation and to process the second signal for touch sensing of a passive touch object proximate to the capacitive sense array in a second mode of operation. The second signal is unsynchronized with the first signal.
