Abstract :
To meet the interest in low power, low cost and small volume, uncooled Infrared Focal Plane Array(IRFPA) and Readout Integrated Circuit(ROIC) with ADC are both emphases for the third generation IRFPA. This paper presents a prototype verification of ROIC with a 14-bit column-level ADC for pyroelectric array. The architecture of ADC is not sensitive to comparator´s delay. Therefore, low power and low noise design can be achieved. A prototype of ROIC with column-level ADC is implemented with a 0.5μm DPTM process. And the circuit can be expended to 384×288 array operating at 60Hz. The current of each column ADC is about 6μA.
