Increasing pixel conversion gain in CMOS image sensors |
摘要 |
A pixel sensor system includes a photo-sensor, an output amplifier, and a feedback capacitor. The photo-sensor is configured to receive photons and to convert the photons into charge. The output amplifier has at least two transistors in a cascoded configuration. The amplifier converts the charge into electronic signal. The feedback capacitor is disposed between the photo-sensor and an input of the output amplifier.
