Enhanced imaging arrays using a sigma delta ADC in Si CMOS for each array pixel


Journal Article

Recently we have demonstrated a compact current input oversampling modulator for a scalable high frame rate focal plane arrays that enable frame rates over than 100kfps operating in continuous imaging mode. All the circuits including data lines and detectors were laid-out to fit into 125um × 125um space using 0.8um 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.
