SUMMARY
The charge shift in Charge-Coupled Devices (CCDs) occurs through a process involving deep potential wells created under pixels. By applying a large voltage to the gate above the pixel, the MOS capacitor is biased into deep depletion, allowing charge to be moved. The charge is transferred stepwise by turning off the voltage on the source pixel while maintaining it on the target pixel, facilitating the movement of charge until it reaches the output stage of the CCD. This method is crucial for the effective operation of CCDs in imaging applications.
