Performance evaluation of an innovative integrated charge-sensitive preamplifier with dynamic range booster

Abstract

In this work we present an innovative all integrated solution, which incorporates on the same chip both a low-noise low-power charge-sensitive preamplifier and an integrated range booster with second-order effect compensation. The booster is based on a particular Time-to-Amplitude Converter which generates analog signals whose amplitude is directly proportional to the energy of the events that caused saturation (ions, energetic charged particles). In this way a dynamic range from a few keV to more than 800 MeV is obtained.
