Dual stage charge-sensitive amplifier with constant-current feedback for Time-over-Threshold processing dedicated for silicon strip detectors

This paper presents a dual stage charge-sensitive amplifier designed for long silicon strip detectors. It allows to obtain a linear Time-over-Threshold processing using constant current feedback for charge and interaction time measurements when working with large capacitance sensors (e.g. C_det=30 pF). The paper includes details of architecture and simulation results.
