G. Bertuccio et al., NEW PERSPECTIVES IN HIGH-SPEED LOW-NOISE CHARGE AMPLIFIERS WITH ULTRA-WIDE-BAND HETEROJUNCTION FETS, Nuclear physics. B, 1995, pp. 591-598
The analysis of the noise properties of heterojunction field effect tr
ansistors open the perspectives in designing charge preamplifiers oper
ating at short shaping times with good noise performance. We presents
the characteristics of these devices, the expected performance and som
e experimental results on prototypes of HEFT charge preamplifiers.
