Abstract :
The influence of the order n of a semi-Gaussian CR-(RC)n shaper on the signal-to-noise ratio of a read-out system, subject to detector 1/f and 1/f2 noise, is presented by the author. Normalised equivalent noise charges, ENC(n), as a function of n for the 1/f and 1/f2 noise, respectively, are calculated and presented. An alternative solution to circumvent the problem of the singularity in the Beta function is discussed, which is related to the 1/f noise. Conclusions and some guidelines are derived from the obtained data
