Abstract

A new multi-channel Waveform Sampling Front-End (WSFE) Application Specific Integrated Circuit (ASIC) for Positron Emission Tomography (PET) has been developed to digitize signals from scintillating crystals at an early stage to suppress noise while facilitating signal processing. Each channel of the chip consists of a preamplifier, a variable gain amplifier (VGA) and a fast Analog to Digital Converter (ADC). This multi-channel chip will be used to readout each pixel of a phoswich detector based on GSO scintillators coupled individually to a multi-array Avalanche Photodiode (APD). Two WSFE ASIC have been developed together with some low noise preamplifiers in a separate chip.
