In this paper a new high gain bandwidth (GBW) and low power folded cascade OPAMP is presented. It has been implemented and layouted by CADENCE software in 0.18μm. Its DC gain is 82db and its bandwidth is 200MHz. Power consumption is one of the main design challenges in very-lowvoltage high-speed analog integrated circuits. In this paper, different techniques to reduce the power consumption in l...

Pedestrian crowds are not homogeneous. One common distinguishing characteristic is the membership in social groups based on friendship or families, for example. It important to understand how these affect pedestrian dynamics inform their consideration safety planning. Despite previous work groups, there a paucity of controlled experiments effect under normal conditions which crucial delineate r...

The possibility to couple train units into consists, which can be vehicles or platoons, has been proposed improve, among other, average passenger speed, energy efficiency, and railway infrastructure capacity utilization. We systematically review categorize the technologies application of coupling identifying different generations coupling, are used for operations. requirements, compatibility in...

Wind farms usually produce power irregularly, due to unpredictable change of wind speed. Accordingly, we should determine the penetration limit of wind power to consider stability of power system and build a facility to control the wind power. The operational limit of wind power is determined as the minimum between the technical limit and the dynamic limit of wind power. The technical limit is ...

Despite excellent high frequency and high speed performance, current-feedback operational ampli ̄ers (CFOAs) generally exhibit poor common-mode rejection (CMRR) properties, which limit their utility [Analogue IC design: The current mode approach, IEE Circuits and Systems Series, Peter peregrinus, 1990]. A novel current feedback operational ampli ̄er (CFOA) with improved performance is presented. ...
