Abstract :
The authors present a new image sensor with a chopper-stabilized edge detector and a correlated-double-sampling readout circuit, based on a 2-μm BiCMOS technology for pattern recognition neural network VLSI applications operating at 77 K. With the chopper-stabilized edge detector and the correlated-double-sampling readout technique, the two-dimensional photodiode array, which can be efficiently built with only one readout circuit, provides a bidirectional edge detection capability for high resolution image sensing applications operating at 77 K
