Dual Speed Read Out Integrated Circuit (ROIC)

Nu-Trek is proposing a revolutionary two-speed, 30 Hz/960 Hz, digital readout out integrated circuit (DROIC) that simultaneously provides very high resolution images (18-20 bits) at 30 Hz and lower resolution images (10-12 bits) at up to 960 Hz. Power consumption is about 50 mW for a moderate format DROIC. This performance is unprecedented and will enable a widespread implementation of dual speed IR cameras. The dual speed IR cameras will be able to detect incoming munitions, which are presently very hard to detect. The DROIC has a revolutionary Mixed Mode Counter, which enables both high resolution and high speed operation. The design also takes advantage of an ultra -low power analog to digital converter technology (7 mW for a 14-bit, 20 MSPS ADC) that Nu-Trek has previously developed. In Phase I a prototype DROIC will be designed and fabricated. In Phase II a full scale DROIC will be fabricated and demonstrated in a camera.
