• abstract: A standard-CMOS 2048-pixel linear image sensor with electronic shutter function and random pixel access is presented. As sensing element a floating n-well PMOS transistors with high photosensitivity is used. The devices operates with a single 5V supply and a single external clock. It exhibits a wide dynamic irradiation range of 177dB with integration time ranging from 1.4µs to 4s. The 33V/µJ/cm2-responsivity sensor has a peak SNR of 81dB and operates up to 125°C with a TC of 5.1mV/°C. The IC integrates all bias, control, electronic shutter, dark current cancellation, and readout electronics.
