CMOS image sensor including tunable read amplifier

摘要: CMOS image sensor is realized, wherein a pre-amp amplifies the voltage of photo detector, and main amp output pre-amp. And adjustable for receiving also optimizing swing. With amps, low sensitivity detector can be amplified more, high less, which enables to adjust gain each from low-sensitive high-sensitive detector. The information adjusting amps stored in latches chip, include laser-blown fuses or electric fuses. In doing so, stacked over access device. particular, repairable, failed replaced with non-failed
