Abstract

We present a versatile method for signal processing as an alternative to conventional methods using discrete front-end electronics. A new Waveform Sampling Front-End (WSFE) ASIC for Positron Emission Tomography (PET) has been developed to digitize signals at an early stage. Each channel of the chip consists of a preamplifier, a variable gain amplifier (VGA) and a fast Analog to Digital Converter (ADC) per channel. Two such chips have been designed and experimental results are presented in this paper.

PET波形采样前端专用集成电路的研制

我们提出了一种通用的信号处理方法，作为使用离散前端电子器件的传统方法的替代方法。开发了一种用于正电子发射层析成像(PET)的新型波形采样前端(WSFE) ASIC，用于早期信号数字化。芯片的每个通道由前置放大器、可变增益放大器(VGA)和每个通道的快速模数转换器(ADC)组成。本文设计了两种芯片，并给出了实验结果。
