G. Bertuccio et al., A FULLY INTEGRATED LOW-NOISE HEMT CHARGE PREAMPLIFIER, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 365(2-3), 1995, pp. 592-595
The design criteria of the first fully integrated charge preamplifier
completely based on HEMTs, together with few preliminary tests of the
circuit, has been already presented by the authors [G. Bertuccio et al
., Nucl. Instr. and Meth. A 338 (1994) 582]. In the previous work the
circuit was tested directly on wafer using coplanar probes. In this Le
tter we present a more accurate characterisation of the amplifier, inc
luding its noise and linearity. The results here presented have been o
btained with the amplifier diced and bonded in a suitable package for
low noise applications.
