High speed high dynamic range digital ROIC for LW infrared FPAs

Abstract

A high speed and high dynamic range digital ROIC for infrared FPA detectors is proposed. With using pixel-level ADC and parallel high speed transmission technology, frame rate and dynamic range of the digital ROIC is greatly improved. A 384×288 digital ROIC with pixel parallel charge packet counting ADCs and 4 parallel transmission channels is designed and fabricated using 0.11μm CMOS technology to verify the proposed ROIC architecture. With the proposed ROIC, a high speed high dynamic range infrared FPA detector is achieved with a frame rate of up to1000Hz and a dynamic range of up to 85dB.
