Paper Abstract

A noise model for detectors operated in the capacitive discharge mode is presented. It is used to analyse the noise performance of the ESO nested timing readout technique applied to a linear 32 element InSb array which is multiplexed by a silicon switched-FET shift register. Analysis shows that KTC noise of the videoline is the major noise contribution. It can be eliminated by weighted double correlated sampling. Best noise performance of this array is achieved at the smallest possible reverse bias voltage (< 20mV) whereas excess noise is observed at higher reverse bias voltages.
