We present a vision chip architecture with column-level photo-amplification of optical data signals for optical wireless local
area networks (LANs) to reduce the pixel area. Based on the architecture, we have fabricated a prototype vision chip in a
standard 0.8 μm bipolar complementary metal-oxide-semiconductor (BiCMOS) technology. The device offers position detection
of other optical transceivers in the LAN and 4-ch concurrent high-speed optical data acquisition. A data rate of 400 Mbps
was demonstrated. The pixel size was 125 μm square, which can be shrunk to smaller than around 60 μm square in 0.35 μm or
more advanced BiCMOS or CMOS technologies. 相似文献
