    Abstract: In an exemplary embodiment, an apparatus includes a sensor integrated circuit (IC) that is adapted for ambient light sensing (ALS) and/or proximity detection. The sensor integrated circuit (IC) includes an integrated analog-to-digital converter (ADC) that is adapted to convert at least one signal related to ambient light sensing (ALS) and/or proximity detection to at least one digital signal, and an integrated light emitting diode (LED) driver that is adapted to drive at least one LED. The sensor IC also includes an integrated power management unit (PMU) that is adapted to reduce power dissipation of the sensor IC by running at a low duty cycle the integrated LED driver and the integrated ADC.

    Abstract: An LCD controller includes a charge pump circuit for generating a charge voltage responsive to an external voltage and a clock signal. An oscillator generates the clock signal responsive to at least one bias voltage. The oscillator has a high power mode of operation and a low power mode of operation. Bias circuitry for applies the at least one bias voltage to the oscillator. The at least one bias voltage is applied to the oscillator from an external source in the high power mode of operation and the at least one bias voltage is applied to the oscillator from a source within the oscillator in the low power mode of operation. An LCD driver voltage circuit generates a plurality of LCD driver voltages for driving segments of an LCD display responsive to the charge voltage.
