摘要
设计了一个应用于PET探测器信号读出的IC模块,具有可变增益的功能以改善输出非一致性,同时拥有很低的输入阻抗,实现了低噪声特性。文章描述了电路的结构,着重阐述了电路设计以及性能。
This paper is about an IC chip which is used for readout in PET detector. This device features a low-noise, low-impedance, variable gain preamplifier to correct for non-uniformity. In this article we describe the IC architecture that will be implemented for PET , with a special emphasis put on the designs and the measured performance.
