Theory of CCD transfer noise from a circuit model

The transfer function and noise of a CCD can be accounted for by a simple block model of the elementary cell. From the analysis of an
n
-cell device, the noise properties of the output signal are derived in both the frequency and the time domain. The approach requires no approximations to calculate the power spectral density and amplitude variance so that the validity of asymptotic expressions can be evaluated. The model lends itself easily to include noise sources other than the transfer noise.
