摘要:The International Linear Collider (ILC) expresses a stringent requirement for high precision vertex detectors (VXD). CMOS pixel sensors (CPS) have been considered as an option for the VXD of the International Large Detector (ILD), one of the detector concepts proposed for the ILC...

摘要:CMOS Active pixel sensors (CMOS APS) are attractive for use in the innermost layers of charged particle trackers, due to their good tradeoffs among the key performances. However, CMOS APS can be greatly influenced by random telegraph signal (RTS) noise, which can cause particle t...

摘要:In this paper, a DC-coupling readout circuit is presented in order to readout the signal from CdZnTe detectors. A differential stage is added in CSA to compensate the leakage current introduced by the CdZnTe crystal. A compact shaper is designed to achieve low area with wide...

摘要:The successive approximation register-analog to digital converter (SAR-ADC) is widely used in the CdZnTe-based gamma-ray imager because of its outstanding characteristics of low power consumption, relatively high resolution, and small die size. This study proposes a digital ...

摘要:This paper presents a 12-bit 2 MS/s pipelined successive approximation register (SAR) ADC for CZT-based imaging system. The proposed ADC is divided into a first-stage 6-bit SAR-based Multiplying Digital Analog Converter (MDAC) and a second-stage 8-bit SAR ADC. The first-stage MDA...

摘要:Empirical studies on the spatial structures in several real transport networks reveal that the distance distribution in these networks obeys a power law. To discuss the influence of the power law exponent on the network's structure and function, a spatial-network model is pr...

摘要:Recently, Li et al. have concentrated on Kleinberg's navigation model with a certain total length constraint Λ= cN , where N is the number of total nodes and c is a constant. Their simulation results for the 1- and 2-dimensional cases indicate that the optimal choice f...

摘要:The Modularity Q is an important index for identifying the community structure in complex networks. Maximizing Q has been proved to be an NP problem and it can only be achieved by heuristic algorithms. In this paper, the modularity maximization problem is proved to be a nonco...
