Popis: | This paper presents a 128 × 128-pix high-speed PbSe-CMOS uncooled MWIR imager with pixel digital output. The proposed in-pixel A/D converter based on integrate-and-fire modulation achieves good linearity even at 20 Meps thanks to its soft-reset mechanism. Class-AB CMOS circuits are proposed to keep static power consumption below 10 μW/pix. Each DPS cell also includes its own analog reference and bias generator. The resulting pixel digital-only I/O interface ensures low crosstalk at the FPA level. From post-layout simulation results, the imager is capable of delivering 14 bit up to 1 kfps or alternatively 4 kfps up to 10 bit. The presented MWIR imager is currently being integrated in the 0.18-μm 1P6M CMOS technology from X-FAB. |
