A CMOS Imaging Diversity Receiver Chip with a Flip-Chip Integrated Detector Array for Optical Wireless Links

“…The reduction in capacitance due to detector segmentation widens the channel bandwidth and reduces f 2 receiver amplifier noise components yielding higher receiver sensitivity. Integrated CMOS imaging receivers for optical wireless links have been demonstrated in [1] with CMOS-based detectors limiting the transmission wavelength to the 780-980nm band where eye safety regulations limit transmit power levels.…”
