Abstract
In various embodiments, an electronic image sensor having extended dynamic range comprises, for example, a pixel circuit and a column readout circuit. The column readout circuit includes, for example, a correlated double-sampling (CDS) capacitor, one or more CDS clamp switches, a single slope analog-to-digital converter (ADC) circuit, and a column memory. Other devices and methods are disclosed.
