A sparse architecture low power gated integrator for use with germanium gamma-ray spectrometers in remote geochemistry measurements

Protocol circuits of a low-power gated integrator for use with germanium gamma-ray spectrometers in remote locations have been developed. The gated integrator is constructed from three very simple subcircuits. With a power consumption of less than 250 mW, the low count rate spectroscopy performance of this gated integrator is comparable to that of a conventional pulse shaping amplifier at energies of 1 MeV and greater.<
