Abstract
An image sensor includes readout circuits coupled to read out integrated light signals from pixels via bitlines respectively. Each readout circuit includes a correlated double sampling (CDS) circuit, followed by an analog-to-digital converter (ADC). At least two pixels of a row share a bitline and an associated readout circuit. The ADC operates concurrently with the CDS circuit, such that their operating periods are substantially overlapped with each other.
