US08502899B2 Solid-state imaging device, imaging device, electronic equipment, A/D converter and A/D conversion method
In a reference signal comparison AD conversion scheme, a reference signal SLP_ADC and each of P and D phases of a pixel signal voltage Vx are compared. A count clock CKcnt1 is counted based on the comparison result. The counting result data is converted into signal data Dsig, i.e., the difference between the P and D phases, which is also subjected to CDS.
