Design of a low noise, self-triggered, monolithic preamplifier dedicated to silicon trackers and X-β imaging

Abstract A monolithic and triggerable charge amplifier has been implemented in a 1.2 μm CMOS technology. Initially developed for the LEP-DELPHI spectrometer (CERN), this architecture is also potentially useful for X and β imaging due to its noise performances (ENC = 110 e − rms + 10 e − rms/pf), low power consumption (Pd = 1.5 mW/channel), internal triggerability and shaping time adjustability between 1 and 2 μs.
