Abstract :
An amplifier chain for a silicon strip detector was investigated for an actual TEG (test element group) design. Using a bipolar SST (super-self-aligned technology) process, a low-power preamplifier was fabricated with a wide bandwidth. The preamplifier shows high gain and low input impedance, owing to an internal gain stage in the feedback loop of the amplifier. A fast shaping amplifier gave an equivalent input noise of less than 100 electrons with an input capacitive load of 10 pF and a shaping time 10-20 ns
