English abstract:
Exploiting the benefits of PIN photodiodes, a correlating detector and a novel difference integrator concept were realized in a single-chip range-finder solution. The PIN photodetector performing already internal modulation has a responsivity of R=0.30A/W at 660nm. A bandwidth of f3dB=250MHz with correlation gates on thin oxide, respectively 500MHz on field oxide were achieved. Both challenges of the distance measurement - high sensitivity for signals in the order of nW and accuracies of 1.6% (1.7%) for 10m (15m) - could be reached. the measurement range goes from 20cm to 15m. The chip was realized in a modified 0.6μm BiCMOS process. Effective pixel size is ~250x170μm2 including the photoreceiver of ~100x100μm2 resulting in a fill factor of ~24%.
