Urban rail transit systems are rapidly developing around the world. Due to a great deal of urban traffic pressure, improving the efficiency and capacity of urban rail transit systems is an increasing demand. Because it is a key subsystem of urban rail transit systems, communication-based train control(CBTC) is an automated train control system that makes use of train–ground wireless communicati...

Abstract MOS Current-Mode Logic (MCML) is usually used for high-speed applications. However, almost all MCML circuits are realized with dual-rail scheme. The dual-rail logic circuits increase extra area overhead and the complexity of the layout place and route. Moreover, little standard cells of the dualrail logic circuits have been developed for place-and-route tools, such as Cadence Encounter...

At present, there are few research results on the seismic response of track system railway suspension bridges, and relevant has not yet formed a certain standard. In order to provide reference for development industry standards design seamless lines based large-mass method multi-point excitation, taking China’s longest high-speed bridge-Wufengshan Yangtze River Bridge as engineering background,...

An ultra low-power high-speed rail-to-rail buffer amplifier with improved current summing circuit is proposed for LCD source drivers. By placing two complementary differential pairs in parallel, it is possible to obtain a rail-to-rail input stage. Then, a current summing circuit with two embedded comparators is proposed. With the proposed current summing circuit, the output stages will be turne...
