Abstract :
The noise performance of digital correlated double sampling (DCDS) for readout of charge-coupled devices (CCDs) with dominant white noise is presented. The trade-offs between analogue and digital signal filtering and the impact on the sampling rate are investigated and numerically simulated for realistic systems. The results can be used to select the signal bandwidth, the settling accuracy and the ADC sampling rate for optimal DCDS noise performance.
