Abstract
We report on the design and measurements of an analog front-end readout electronics dedicated for silicon microstrip detectors with relatively large capacitance of the order of tens pF for time and energy measurements of incoming pulses. The front-end readout electronics is required to process input pulses with an average rate of 150 kHz/channel with low both power consumption and noise at the same time. In the presented solution the single channel is built of two different parallel processing paths: fast and slow. The fast path includes the fast CR-RC shaper with the peaking time t(p)=40 ns and is optimized to determine the input charge arrival time. The slow path, which consists of the slow CR-(RC)(2) shaper with the peaking time t(p)=80 ns, is dedicated for low noise accurate energy measurement. The analog front-end electronics was implemented in UMC 180 nm CMOS technology as a prototype ASIC AFE, The AFE chip contains 8 channels with the size of 58 mu m x 1150 mu m each. It has low power dissipation P-diss=3.1 mW per single channel. The article presents the details of the front-end architecture and the measurement results. (C) 2014 Elsevier B.V. All rights reserved.
