A low power readout integrated circuit (ROIC) for 512 × 512 cooled infrared focal plane array (IRFPA) is presented. A capacitive trans-impedance amplifier (CTIA) with high gain cascode amplifier and inherent correlated double sampling (CDS) configuration is employed to achieve a high performance readout interface for the IRFPA with a pixel size of 30 × 30 μm2. By optimizing column readout timing and using two operating modes in column amplifiers, the power consumption is significantly reduced. The readout chip is implemented in a standard 0.35 μm 2P4M CMOS technology. The measurement results show the proposed ROIC achieves a readout rate of 10 MHz with 70 mW power consumption under 3.3 V supply voltage from 77 K to 150 K operating temperature. And it occupies a chip area of 18.4 × 17.5 mm2.

A readout integrated circuit (ROIC) of infrared focal plane array (IRFPA) with low power and low noise is presented in this paper. It consists of a 384 × 288 pixel array and column-level A/D conversion circuits. The proposed system has high resolution because of the odd–even Analog to Digital Conversion (ADC) structure, containing correlated switches design, multi-Vth amplifier design and high speed high resolution comparator design including latch-stage. Designed and simulated in 0.35-μm CMOS process, this high performance ROIC achieves 81.24 dB SNR at 8.64 KS/s consuming 98 mW under 5 V voltage supply, resulting in an ENOB of 13.2-bit.
