A 0.8 μm Nonacell for 108 Megapixels CMOS Image Sensor with FD-Shared Dual Conversion Gain and 18,000e- Full-Well Capacitance

A 0.8μm-pitch 108 megapixels (Mp) ultrahigh-resolution CMOS image sensor has been demonstrated for mobile applications. The Nonacell was developed through a 3x3 color filter and 1x3 shared pixel structures which can be operated the 3 binning mode to achieve 12Mp resolution and improve low-illuminance signal-to-noise ratio (SNR) characteristic. The full-well capacity (FWC) of Nonacell was achieved up to 18,000e- using FD-shared dual conversion gain (CG) technology, and excellent high-illuminance SNR was demonstrated.
