Electronics Letters, 2014•Wiley Online LibraryThe 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.
