   Abstract:
   Recently we have demonstrated a compact current input oversampling modulator for scalable high frame rate focal plane arrays that enables frame rates over 100 kfps operating in continuous imaging mode. All the circuits including data lines and detectors were laid-out to fit into 125 μm×125 μm space using 0.8 μm CMOS technology. This compact converter also provides improvement in noise filtering performance over imagers that use capacitance at each pixel to convert detector current to voltage. This technique may allow noisy detectors to be used at high temperatures with good image quality
