A detector module for high-resolution animal PET with depth-of-interaction (DOI) information has been proposed. It consists of finely granulated scintillators individually coupled to each pixel of a multi-array Avalanche Photodiode. Scintillators of different decay times are stacked as in a phoswich detector to provide DOI information by pulse shape discrimination. Since each channel will be readout individually for high sensitivity and spatial resolution, a power efficient and highly integrated multi-channel Waveform Sampling Front-End (WSFE) Application Specific Integrated Circuit (ASIC) have been developed. Each channel of the WSFE ASIC consists of a preamplifier, a variable gain amplifier and a fast Analog to Digital Converter to digitize signals at an early stage.
