Abstract
Described herein are optical proximity detectors, methods for use therewith, and systems including an optical proximity detector. Such optical proximity detectors include an analog front-end and a digital back-end. In certain embodiments, the digital back-end includes a dynamic gain and phase offset corrector, a cross-talk corrector, a phase and magnitude calculator, and a static phase offset corrector. The dynamic gain and phase offset corrector corrects for dynamic variations in gain and phase offset of the analog front-end due to changes in temperature and/or operating voltage levels. The crosstalk corrector corrects for electrical and/or optical crosstalk associated with the analog front-end. The phase and magnitude calculator calculates phase and magnitude values in dependence on the corrected versions of digital in-phase and quadrature-phase signals received from the analog front-end. The static phase offset corrector corrects for a static phase offset of the optical proximity detector.
