Corrugated Quantum Well Infrared ROIC technology (CROIC)

The Corrugated Quantum Well Infrared ROIC (CROIC) FPA is the centerpiece for a potentially revolutionary technical break-through required in the successful development of Broadband C-QWIP sensors with FPA format of greater than 2000 x 2000 pixels. The Corrugated Quantum Well Infrared Rios"s innovative design will allow breakthroughs to high sensitivity C-QWIP detectors with adaptive/precision dynamic range control and novel noise reduction circuits. Figure 1 illustrates the ROIC Circuit which provides adaptive charge skimming, enhanced dynamic range, subframe averaging noise reduction, and shorted pixel mitigation for C-QWIP Detectors.Cyans CROIC architecture allows high voltage detector biasing so the C-QWIPS detectors can reach peak responsivity. The CROIC will be designed to support single color P on N or N on P polarity detectors and also support dual band C-QWIP arrays thanks to a unique high bias capable dual polarity input circuit.
