The results of engineering an intelligent preamplifier for HPGe
gamma-detectors are presented. An intelligent preamplifier is a low-noise,
high-speed resistive feedback charge-sensitive preamplifier with a built-in
microcontroller and additional units that enable control of preamplifier and
detector parameters. It also allows to manage performance of the internal
testing pulser, sensor of liquid nitrogen level in Dewar, humidity, pressure
and temperature sensors in a sealed preamplifier section. Intelligent
preamplifier operation, setup and parameter measurements are controlled by a
software.
