A 16-bit Pixel-level ADC Based on Ring Oscillator for 30μm Pitch 320 ×256 LWIR FPAs
A low-power and high-dynamic range ADC-based 320×256 size digital readout integrated circuit for infrared focal plane arrays is proposed in this paper. Compared with the traditional structure, the proposed pixel-level ADC structure based on ring oscillator can achieve higher dynamic range and lower power consumption. The design is based on 0.18μm 1P5M CMOS process, and the pixel circuit pitch is 30μm. The simulation results show that the average power consumption of the proposed single pixel-level ADC is 1.36μW. The charge handling capacity of the pixel is 2.8Ge-; the dynamic range is 96.32dB, and the non-linearity is 0.76%.
