CMOS switches are one of the main components of today's analog circuits. Among the many types of non-idealities that can affect the performance of the switch, its leakage current is of utmost importance. In order to reduce the leakage current or equally increase the OFF resistance of any switch, a novel technique is presented in this paper. The proposed technique employs the body effect to incr...
In this paper, design, analysis and fabrication of a low loss capacitive RF MEMS shunt switch, which made on the coplanar waveguide transmission line and alumina substrate in the frequency band of 40-60 GHz, is presented. The CPW is designed to have 50Ω impedance matching on the alumina substrate. Then the desired switch is designed with appropriate dimensions. Afterward the important par...
Moving car on rough road suddenly gets out of its way for some reason and moves to the edge of the road at the same speed. Since the most important factor in car overturning is vertical acceleration in the wheels and car speed and road conditions determine the vertical instantaneous acceleration, brake system according to change of the spring length is designed in such a way that by monitoring ...
The flange climb derailment is one of the cause of derailment for a typical switch. The derailment for the switch is a complex phenomenon since the contact area is changing dynamically. The contact angle between the wheel flange and the switch point is investegated in terms of the risk on the derailment. The contribution of this study is proving that UIC716R standard recommendation about the sw...
A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...
The intelligentization, informationization, and internalization of power system infrastructure equipment are the key technologies to achieve low-carbon transformation system. To tackle low degree intelligence internet in monitoring early warning mechanical faults disconnecting switch, this paper designs an intelligent for switch operation status based on sensing technology. Torque sensors, angl...
در این پروژه تلاش می شود کلیدزنی سریع حالت های کوانتومی را با استفاده از خصوصیات اسپین بررسی نمائیم. اندرکنش اسپین و میدان الکتریکی برای تغییر واهلش مورد بررسی قرار می گیرد. د این بررسی تلاش خواهد شد با استفاده از ماهیت کوانتومی اسپین و مدیریت اسپین کلیدزنی حالت کوانتومی با کمترین انرژی و کمترین سرعت عملی شود. در این تحلیل معادلات دینامیکی اسپین تهیه شده و با استفاده از اندرکنش با نور پارامترها...
in this research, the structural behavior of timber and concrete sleepers in a standard railway turnout is evaluated, in the case of raising speed. in approaching this evaluation, current practices in the structural analysis of sleepers are surveyed and then, the sensitivity analysis with abaqus software is made based on selected criteria (bending and shear stresses as well as contact pressure)...
