Abstract
The image sensor makes use of a distributed amplifier having its non-inverting input provided by a pixel amplifier transistor, and its inverting input and output provided in the pixel's column circuitry. The distributed amplifier is directly integrated with the image sensor's ADC circuit, and sampling and autozero are performed in a single step, thus reducing the number of noise contributions made by the components of the image sensor's readout chain.
