Through Silicon Via Interconnects are usually protected with liners. A research on liners was done and conclusion made that they experience reliability problems like hoop stress which put them and the Through Silicon Via in danger. Simulation using Analysis Software was done on Silicon Dioxide liner. A Through Silicon Via of internal radius five micrometers, silicon liner of thickness two micrometers...
In this paper, we analyze the shortcomings of traditional Doherty power amplifier (DPA) structure and propose an improved load modulation structure; Improving back-off efficiency of Doherty amplifier by using pre-matching technology. Also, the linearity is improved by using the in-band error cancellation technique of the Doherty amplifier. We implemented a Doherty amplifier with Cree's 10 W GaN HEMT...
In light of China's traffic accident status much, this paper focuses on the problem of reducing the occurrence of traffic accidents. Based on the traffic accident data within a year in certain section of Tianjin, this paper studies the application of fuzzy assessment method in analysis of time distribution of traffic accidents. We use fuzzy assessment method to get the time distribution order of the...
According to the characteristics and requests of data analysis of traffic information, data mining techniques are put forward to apply to the management and decision-making of traffic information. Based on this foundation, an integrated model of the traffic information intelligent analysis and decision support is further given. This model has data mining techniques and data warehouse at its core,...
