This paper presents the design and characteristics of a front-end readout application-specific integrated circuit (ASIC) dedicated to a multichannel-plate photodetector coupled to LYSO scintillating crystals. In our configuration, the crystals are oriented in the axial direction readout on both sides by individual photodetector channels allowing the spatial(More)
This paper presents the design of a low-power multi-channel time-based analog-to-digital converter (ADC) for the instruments dedicated to high-energy physic experiments and biomedical imaging applications. The proposed ADC is realized by using two-step conversion scheme: the voltage-to-time conversion (VTC) and the digital-to-time conversion (TDC). In VTC,(More)
This paper presents the design of a wide-range multi-channel time-to-digital converter (TDC) for high-energy physics and biomedical imaging applications. The TDC architecture is based on coarse-fine two-level conversion scheme. Double 10-bit gray counters are designed for coarse conversion while a multiphase sampling technology based on array of(More)
