Performance test of preamplifiers for multi-gap resistive plate chamber (MRPC)

In this paper, 3 types of preamplifier for MRPC (Multi-gap Resistive plate chamber) are developed and compared in the performances. The main role of the front-end electronics (FEE) for MRPC is to measure the arrival time, which means the time when the particle goes through MRPC. So preamplifier used in the FEE must have a good time performance such as a small propagation delay jitter and fast rise time. We develop 3 types of preamplifier using voltage-feedback op amp (VFA), current-feedback op amp (CFA) and transimpedance amp, respectively. We make performance test with 3 types of preamplifier, including jitter, rise time, linearity, noise figure and input impedance and compare results of performance measurements. With the test results, current-feedback noninverting amplifier is suitable for MRPC.
