  • CHARGE PUMP CELL WITH IMPROVED LATCH-UP IMMUNITY AND CHARGE PUMPS INCLUDING THE SAME, AND RELATED SYSTEMS, METHODS AND DEVICES
    Publication number: 20230231474
    Abstract: A charge pump cell for a charge pump is disclosed that may exhibit improved latch-up immunity. A circuit may be arranged at the charge pump cell to apply a voltage to a bulk contact of a charge transfer transistor of such a charge pump cell at least partially responsive to a relationship between a voltage at a first terminal of the charge transfer transistor and a voltage at a second terminal of the charge transfer transistor. A charge pump including one or more such charge pump cells may include a control loop that is configured to control a pumping signal at least partially responsive to a state of an output voltage of the charge pump.

  • Amplified charge cancellation in a touch sensor, and related systems, methods, and devices
    Patent number: 11604539
    Abstract: A charge compensation circuit is disclosed that provides amplified charge cancellation. A touch controller is disclosed that includes such a charge compensation circuit and may realize improved immunity to baseline capacitance signals that are much larger than a change in capacitance due to proximity of an object. Such a charge compensation circuit may include a capacitor, a driver circuit arranged to apply a pulsed voltage signal to the capacitor, and a current conveyor having a programmable gain and arranged to amplify an initial charge generated by the capacitor in response to the pulsed voltage signal and provide an amplified charge to an output of the charge cancellation circuit.
