Business Wire: CMOSIS and TowerJazz announced 12MP CMV12000 featuring global shutter and a frame rate of 300 fps, said to be best in-class performance. The off-the-shelf image sensor is manufactured in TowerJazz’s Fab-2 in Migdal Haemek, Israel, using its advanced 0.18 µm specialty CIS process. The sensor features 5.5 x 5.5 µm pixels laid out in 4096 x 3072 matrix resembling the APS-C format.
CMV12000 offers a DR of 60 dB, extendable to 90 dB through several HDR operation modes. The sensor pixels have a very low parasitic light sensitivity (1:50,000) enabling high efficiency global shutter operation. One of the unique features of CMV12000 is the novel pixel structure, which combines pipelined global shutter operation with CDS. This technique yields an low noise level below 13 e- and a full well of 13,500 electrons. The global shutter CDS also significantly reduces the sensor's FPN.
CMV12000’s on-chip ADC can be operated at 8-bit, 10-bit or 12-bit resolution. In the faster 10-bit mode, 300 full frames per second are acquired. At 12-bit, CMV12000 still realizes a frame rate of 180 fps. The sensor's advanced architecture allows for row windowing and row sub-sampling. Up to 32 separate partial windows can be defined for an accelerated readout. Averaging several pixels raises these frame rates and increases the dynamic range.
“We highly value our partnership with TowerJazz and its advanced CMOS imaging technology for our innovative products due to the success we have achieved throughout our collaboration. Due to the maturity of their process technology, combined with the design flexibility that they offer, we are able to realize stronger and more reliable performance,” said Luc De Mey, CMOSIS CEO. “In addition, TowerJazz’s long-term investment in R&D and their excellent technical support keeps us at the cutting edge.”
“By combining our worldwide recognized 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,” said Avi Strum, VP and GM of TowerJazz’s Specialty Business Unit.
The new CMOS sensor is suited for a broad range of industrial, movie and TV, traffic monitoring and motion control applications. The Total Addressable Market for industrial sensors is estimated at $750M, out of which the machine vision sensor market is estimated at $200M, according to a report titled, “The Future of Image Sensors Market and Technology Forecasts to 2014,” by Roy Szweda.
Update: As written in comments, the sensor is based on 8T pixel to realize a high-quality fully pipelined global shutter with low parasitic light sensitivity. All 8 transistors together with two storage caps are squeezed into 5.5um FSI pixel in 0.18um process - the pixel layout must be a masterpiece!
There is a nice CMOSIS presentation describing the pixel operation and advantages, presented on Image Sensors Europe conference in March 2010. The 8T pixel operation principle is explained below:
