Abstract
Techniques for using photo detectors as tunable proximity sensors for detection of target objects and ascertaining their distance from the proximity sensors are disclosed. In one embodiment, the techniques may be realized as a proximity sensor system including a photo detector having a first doped region, a gate, a second doped region and a light absorbing region, a control circuitry for generating a plurality of control signals to be applied to the photo detector, and a signal detector to detect an output signal from the photo detector.
