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 10):
The optical proximity detector of  claim 1 , farther comprising the light source that is driven by the drive signal produced by the driver.
