ISBN: 9783659374340 / Angielski / Miękka / 64 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Home monitoring system has become the demand of present day life. Here we have used RF technology to monitor the status and control the ELECTRONIC SWITCHES which can be furthur utilised for designing monitoring systems. The system has been developed to save energy. The system is implemented using modules which are capable of communicating with each other. In the existing method we can control the device like ON/OFF of the device remotely but we cannot know the status of the device whether the device is working or not. In the proposed method we overcome this disadvantage by providing good...

Subthreshold Surface Potential Model for Short-Channel Mosfet
ISBN: 9783659126093 / Angielski / Miękka / 84 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. As a result of aggressive downscaling, short-channel effects (SCEs) become a major threat for future downscaling especially in the sub-100nm region. In order to extend the International Technology Road-map for Semiconductors (ITRS) road-map beyond 100nm, Double-Gate (DG) MOSFET evinces himself as a major promising candidate due to its higher scaling capability. In this book, modelling using a pseudo- two-dimensional (2D) analysis was presented to explore the effect of scaling especially for subthreshold characteristics of short-channel DG and conventional single gate MOSFET.
