Abstract:
An optical proximity detector includes a driver, light detector, analog front-end, sensor(s) that sense correction factor(s) (e.g., temperature, supply voltage and/or forward voltage drop), and a digital back end. The driver drives the light source to emit light. The light detector produces a light detection signal indicative of a magnitude and a phase of a portion of the emitted light that reflects off an object and is incident on the light detector. The analog front-end receives the light detection signal and outputs a digital light detection signal, or digital in-phase and quadrature-phase signals, which are provided to the digital back-end. The digital back-end performs closed loop correction(s) for dynamic variation(s) in gain and/or phase caused by a portion of the analog front-end, uses polynomial equation(s) and sensed correction factor(s) to perform open loop correction(s) for dynamic variations in temperature, supply voltage and/or forward voltage drop, and outputs a distance value.

Claim (Index 6):
The optical proximity detector of  claim 1 , wherein:\n the analog front end includes amplification circuitry that uses one or more gain values to control amplifying of the light detection signal produced by the light detector before the light detection signal is converted to the digital light detection signal or the digital in-phase and quadrature-phase signals; and the digital back-end is adapted to use at least one of the one or more polynomial equations to correct for dynamic variations in at least one of the one or more gain values.
