More Information
Summary:An imaging system includes an array of pixel cells and a plurality of digital memory elements disposed physically separate from and coupled to the array of pixel cells. Each of the pixel cells includes a photodetector, an electrical storage device coupled to the photodetector, and quantization circuitry coupled to the electrical storage device. The photodetector is configured to generate a photo-current in response to light impinging thereon. The electrical storage device is configured to accumulate an electrical charge from the photo-current. The quantization circuitry is configured to convert the electrical charge into an analog quantization event signal. Each of the digital memory elements is in electrical communication with at least one of the pixel cells and is configured to store a digital value in response to receiving the analog quantization event signal from the at least one of the pixel cells.
