Abstract :
This paper demonstrates a compact current input oversampling modulator for scalable high frame rate focal plane arrays. This smart pixel architecture with the proposed compact current input oversampling modulator is intended for scientific imagers with frame rates around 100 kfps operating in continuous imaging mode. All the circuits including data lines and detectors fit into a 125 micron×125 micron cell using 0.8 micron CMOS technology. Test results on a 8×8 demonstration focal-plane-array show operation at over 100 MHz sampling rate which represents a 60 kfps 8 bit per pixel image capture rate
