  • Patent number: 11581693
    Abstract: The disclosure relates to a pulsed laser driver that utilizes a high-voltage switch transistor to support a high output voltage for a laser, and a low-voltage switch transistor that switches between an ON state and an OFF state to generate a pulsed current that is supplied to the laser to generate an output pulsed laser signal. The pulsed laser driver switches the low-voltage switch transistor between the ON state and the OFF state according to an input pulsed signal such that the output pulsed laser signal is modulated according to the input pulsed signal. The pulsed laser driver also utilizes a feedback control module to control the gate terminal voltage of the high-voltage switch transistor to improve the precision of the output pulsed laser signal.

  • Patent number: 9870097
    Abstract: A differential sensing scheme provides a means for detecting one or more touch events on a touch sensitive device in the presence of incident noise. Instead of sensing one touch sensitive channel, such as a row, column, or single touch sensor, multiple touch sensitive channels are sampled at a time. By sampling two nearby channels simultaneously and doing the measurement differentially, noise common to both channels is cancelled. The differential sensing scheme is implemented using simple switch-capacitor AFE circuitry. The originally sensed data on each individual channel is recovered free of common-mode noise. The recovered sensed data is used to determine the presence of one or more touch events and if present the location of each touch event on the touch sensitive device.
