Analog FastSPICE Platform CMOS Image Sensor Verification
CMOS image sensors (CIS) are widely used for imaging in smart phones, tablets, cameras, industrial, medical, and automotive applications. High-level CIS architectures are array-based, similar to memory architectures. The CIS block diagram in this white paper shows the pixel array, the column readout and analog-to-digital converter (ADC) circuitry. The image sensor captures an image with an array of identical pixels, reads the contents of the array, and converts the analog voltages to a digital code for each pixel.
