Imec and Panasonic Present 2k4k/60fps Sensor

Imec presents a CMOS sensor capturing 12b 4000 x 2000 pixel progressive images at 60fps. Based on a stagger-laced dual exposure, the image sensor developed with Panasonic, was processed using imec’s 130nm CMOS process on 200mm silicon wafers to deliver high-speed and high-quality imaging, at reduced output bit rate.

The sensor is based on 4T shared pixel with a pitch of 2.5um and a conversion gain of 70 μV/e-, which allows for both a classical rolling shutter or stagger-laced scanning mode. The sensor has 12-bit column-based delta-sigma ADCs. The stagger-laced scanning method improves imaging sensitivity and realizes a 50% reduction in output data rate by alternating the readout of two sets of horizontal pixel pairs arranged in two complementary checkerboard patterns. The overall power consumption of the imager is less than 2W.

“This is an important milestone for imec to demonstrate our capability to co-design, prototype and manufacture high performance CMOS image sensors in our 200 mm CMOS fab,” commented Rudi Cartuyvels, SVP of Smart Systems & Energy Technologies at imec.
