G. Degeronimo, IN VIEW OF LOW-NOISE AND LOW-POWER GAAS FRONT-ENDS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 410(1), 1998, pp. 124-128
The use of GaAs in front-end electronics for radiation detection syste
ms has been widely investigated by many authors and several prototypes
of GaAs front-ends have been proposed. This work is a review and deep
ening of the criteria for the design of a low noise and low-power GaAs
front-end. Remarks on the choice of the optimum bins point and gate w
idth of the input transistor and on the choice of the shaping an discu
ssed. A comparison of several GaAs FETs in terms of low-frequency nois
e and achievable resolution is also shown. (C) 1998 Elsevier Science B
