Optimal digital correlated double sampling for CCD signals
The noise performance of digital correlated double sampling (DCDS) for readout of charge coupled devices (CCD) 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 t...
متن کاملParallel correlated double sampling technique for pipelined analogue-to-digital converters
Introduction: In a switch-capacitor realisation of the multiplying digitalto-analogue converter (MDAC) used in algorithmic and pipeline analogue-to-digital converters (ADCs), the settling behaviour of the opamp determines the speed and accuracy of the ADC. Fast settling requires high unity gain bandwidth, while accurate settling requires a high DC gain. As gate lengths continue to shorten, high...
متن کاملCharge-based MOS correlated double sampling comparator and folding circuit
A novel charge-based comparator and folding circuit are presented. Correlated double sampling comparison is performed using a log-domain integrator, implemented by a subthreshold MOS transistor with the source coupled to a capacitor. The circuit produces a current that is a logistic function of the change in voltage on the gate, with an input-referred offset voltage that is a logarithmic functi...
متن کاملTime-delay Integration Ccd Readout Technique: Image Deformation
SUMMARY The introduction of electro-optical tracking with CCDs has revitalised the research potential of the transit telescope. Termed the Time-Delay Integration (TDI) readout technique (or drift scanning), this method ooers exceedingly good at-elding performance. While this asset is not disputed, there has been no quantitative analysis of potential drawbacks of the TDI technique. The work pres...
متن کاملDesign of Economic Optimal Double Sampling Design with Zero Acceptance Numbers
In zero acceptance number sampling plans, the sample items of an incoming lot are inspected one by one. The proposed method in this research follows these rules: if the number of nonconforming items in the first sample is equal to zero, the lot is accepted but if the number of nonconforming items is equal to one, then second sample is taken and the policy of zero acceptance number would be ap...
