Abstract:
An imager architecture that utilizes column sampling circuitry that can support pixel-wise automatic gain selection (AGS). The column sampling circuitry samples the pixel output signals directly (e.g., with unity gain) or after amplification in a column level amplifier while supporting correlated double sampling (CDS) in both situations.
