Omnivision to Use BDA FastSPICE

Business Wire: Berkeley Design Automation announces that Omnivision has selected the company’s Analog FastSPICE (AFS) Platform for block-level characterization and full-circuit verification of their single-chip image sensors for consumer and commercial applications.

"We have stringent circuit verification requirements to achieve the high resolutions, low light levels, and resulting image quality of our CMOS image sensors," said T.J. Dai, director of analog and layout at OmniVision. "We selected the AFS Platform because it provides the accuracy and speed that enables us to perform full-spectrum device noise analysis to characterize the quality of our single-chip CMOS image sensor designs."

Bekeley DA's white paper on CMOS sensors simulations shows a transient noise simulation of a comparator, apparently in ramp ADC:
