N. Randazzo et al., A 4-CHANNEL, LOW-POWER CMOS CHARGE PREAMPLIFIER FOR SILICON DETECTORSWITH MEDIUM VALUE OF CAPACITANCE, IEEE transactions on nuclear science, 44(1), 1997, pp. 31-35
We present a low-power CMOS charge preamplifier, suitable for use with
silicon detectors having a medium value of capacitance, Noise conside
rations and a long decay time of the output signal command the use of
unusually large devices such as an input transistor having W = 10 000
mu m and a 7-M Omega feedback resistor. Both of these devices were int
egrated inside the chip, We present and compare theoretical prediction
s together with the results of post-layout simulation and the measurem
ents obtained.
