Abstract :
An active photodiode 4×64 image sensor array was designed and fabricated using a 0.5 μm CMOS process. The sensor includes on-chip timing and control as well as correlated double sampling for readout. The operation of the sensor is selectable between a linear integration mode and a logarithmic mode using the same array of pixels
