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.
