ROIC with Adaptive Reset Control for Improving Dynamic Range of IR FPAs
A new readout integrated circuit involving an adaptive reset control was studied for 2-D infrared focal plane arrays. The integration time of each pixel can be optimized adaptively. Hence, the readout circuit has a wide dynamic range and good signal-tonoise ratio characteristics. The readout circuit was fabricated with a 0.35 μm 2-poly 4-metal CMOS process for a 128 x 128 long wavelength infrared array with a pixel size of 50 μm × 50 μm. The adaptive reset control with two-step background suppression improves the signal-to-noise ratio to 87 dB and the dynamic range to 95.4 dB.
