摘要：
We have developed a new readout circuit for highly sensitive CMOS image sensors. The circuit makes it possible to obtain a high signal-to-noise ratio by effectively transferring signal charges accumulated in the photodiode to a small capacitance. We fabricated and tested a CMGS image sensor with the readout circuit, and confirmed that it has higher sensitivity than conventional passive-pixel CMOS image sensors.
