Abstract
A method of implementing extended range successive approximation analog-to-digital converter (ADC) starts with a readout circuitry acquiring an image data from a row in a color pixel array. ADC circuitry in the readout circuitry then generates an ADC pedestal for the row. Successive Approximation Register (SAR) included in ADC circuitry then stores ADC pedestal. SAR includes a plurality of bits and an additional bit that is a duplicate of one of the plurality of bits. ADC circuitry samples the image data from the row against ADC pedestal stored in SAR to obtain a sampled input data. ADC circuitry then converts the sampled input data from analog to digital to obtain an ADC output value. Other embodiments are described.
