Abstract

The design and results of a radiation hard switched gain charge amplifier optimised for a large dynamic range and large input capacitance are described. The peaking time is 25 ns, dynamic ranges are 0.1–50 minimum ionising particles (MIPs) (high gain) and 1–400 MIPs (low gain), signal to noise (S/N)>10 for Cin<56 pF and radiation tolerance to 10 Mrads(Si) and 4×1013 n cm−2.
