Abstract
A dual operation correlated double sampling (CDS) readout circuit for implementation with a dual-conversion-gain (DCG) pixel is disclosed. The dual CDS readout circuit is capable of switching between a first readout mode that implements digital CDS and a second readout mode that implements analog CDS. In various implementations, the dual CDS readout circuit provides digital CDS operations when the DCG pixel outputs a high conversion gain (HCG) analog output signal. The dual CDS readout circuit may provide analog CDS operations when the DCG pixel outputs a low conversion gain (LCG) analog output signal.
