摘要

The eight-channel ASIC low-noise bipolar transresistance amplifier D0M Ampl-8.3 has been designed on the basis of BJT-JFET technology for gaseous wire detectors used in high-energy physics experiments. The amplifier has differential gain 130mV/μA at 1kΩ, input noise 35 and 60nA r.m.s. at 0 and 60pF input capacitance, respectively, leading/trailing edge 7ns, input resistance ≈50Ω, crosstalks −47dB, dissipated power 160…640mW/chip for ±3…5V supply. The Ampl-8.3 has been accepted for upgrading the Forward Angle Muon System of the D0 experiment (Fermilab, Batavia, USA), the total number of channels is about 50,000.
