Leti cuts noise from image sensors

Dubbed ‘Owly-eyed’, it is based on a patented electrical pixel readout architecture that can be integrated in image sensors, which Pyxalis will offer it in its next range of CMOS sensors.

“In this common lab with Pyxalis, we’ve developed a low-noise image technology that provides state-of-the-art advanced imaging for next-generation applications in a wide range of markets and industries,” said Leti CEO Marie Semeria. “This CMOS-based device, which can be adapted for multiple uses, is another example of how Leti’s innovations make our partners more competitive in their industries.”

This technology “will allow us to establish a new performance standard in image sensors addressing the growing demand for low-light applications in the surveillance, biomedical, science, defence and aerospace markets,” said Pyxalis CEO Philippe Rommeveaux.

In a demonstrator, <0.5 e(rms) temporal read noise has been achieved on a VGA format CMOS image sensor implemented in a standard CMOS process without any process refinements and only through circuit optimisation .

It will be on how at Vision 2016 in Stuttgart next week (Hall 1 booth H01).
