CMOSIS, an independent developer and supplier of high end CMOS image sensors for professional imaging applications, and global speciality foundry, TowerJazz have announced a new image sensor using an advanced 0.18 µm specialty CIS process.
The 12-megapixel CMV12000 is a member of COMOSIS' CMV CMOS image sensor and is manufactured in TowerJazz's Fab-2 in Migdal Haemek. The sensor features 5.5 x 5.5µm pixels laid out in a high resolution 4096 x 3072 matrix resembling the APS-C format. It offers high sensitivity and low noise, global shutter and a frame rate of 300fps which provides best in class performance according to CMOSIS. The device is suited for a range of industrial, movie, traffic monitoring and motion control applications.
CMV12000 offers a range of 60dB, extendable to 90dB through several high dynamic range operation modes. The sensor pixels have a low parasitic light sensitivity (1:50,000) enabling high efficiency global shutter operation, which allows the sensor to capture extreme fast moving scenes without image distortion.
The device's pixel structure combines pipelined global shutter operation with correlated double sampling (CDS). This technique, pioneered by CMOSIS, is said to yield an 'unprecedented low noise level' below 13e- and a full well charge of 13,500electrons. The global shutter CDS also significantly reduces the sensor matrix's fixed pattern noise for better image quality. Its on chip a/d converter can be operated at 8, 10 or 12bit resolution.
Dr Avi Strum, vice president and general manager of TowerJazz's Specialty Business Unit, said: "By combining our worldwide recognised leadership in CMOS sensors and pixel technology with CMOSIS' many years of experience in CMOS image sensor design, we are equipped to meet the market's demanding requirements for leading-edge performance, advanced features and reduced die size and price. Together, we are well-positioned to win a significant share of future industrial and professional CMOS image sensor markets."
