Abstract
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.
