CMOS active-pixel image sensors, as well as chargecoupled devices, generate both white noise and 1=f -noise over several decades depending on biasing current, operating temperature, and the characteristics of the process used, limiting the detector dynamic range. Three readout circuits, based on a fully differential cascode operational transconductance amplifier, designed and realized on a standard CMOS 0.7m single polysilicon/double metal process, are proposed for CMOS activepixel imagers. The… CONTINUE READING
