An array of 128×128 digital pixel sensors (DPS) that performs both in pixel light current integration and analog-to-digital conversion is presented. The pixel fabricated on a DP4M CMOS process provides a digital output of ultraviolet light intensity via an integrated multiple-channel bit-serial (MCBS) ADC. Due to low light current (~pA) of ultraviolet focal-plane-array, the architecture of capacitive trans-impedance amplifier (CTIA) is used. The proposed readout integrated circuits have a 12-bit resolution, 70dB dynamic range and 99% of linearity.
