TV-type multichannel detectors

“…Charge Injection Device (CID). This imaging device, recently developed by General Electric (15), utilizes an x-y addressed array of charge storage capacitors which store photongenerated charge in MOS inversion regions.…”

A CMOS area image sensor with pixel-level A/D conversion

“…Bipolar junction phototransistor arrays [6], and charge injection arrays [5] have also been used. However, these alternatives can suffer from low resolution due to limited pixel observation time, limited SNR due to analog sensing, and as with CCDs, data is communicated off chip in analog form.…”
