Abstract :
In this paper we present a new VLSI shaper amplifier suitable for multi-anode silicon drift detectors, or other multi-element solid-state X-ray detection systems. The readout scheme has been conceived and developed for demanding applications with synchrotron light sources, such as X-ray holography or EXAFS experiments, where both high count-rates and high energy resolutions are required. The circuit is of time-variant nature, accepts randomly distributed events and features: a finite-width (1.1 μs) weight function, a low-level energy discrimination, a low power consumption (a few mW per channel) and a full compatibility for monolithic integration in CMOS technology
