摘要
A 1/2.7-in 1944 x 1484 pixel CMOS image sensor with double CDS architecture fabricated in a 0.18-mu m single-poly triple-metal (1P3M) CMOS process is described. It operates at 48 MHz in a progressive scanning mode at 60 frames/s for full high-definition (HD) imaging. Two transistors/pixel architecture and low optical stack with double microlenses achieve 14.6ke(-)/lx center dot s sensitivity and 14ke(-) saturation. Double CDS architecture with a high-gain column amplifier realized a low noise floor of 3.5e(rms)(-). Optimized shallow-trench isolation achieved very low dark current of 12.2e(-)/s (60 degrees C). This image sensor also realizes low power consumption of 220 mW.
