This paper demonstrates a fully-silicided ESD protection device design in sub-100nm integrated circuits. No drain ballast resistor required is the most significant feature that makes the new device differ form the conventional ones. Accordingly, a simplified manufacturing process and a reduced device area could be obtained simultaneously. It is believed that the achievements are caused from the...

Electrostatic Discharge (ESD) is generally recognized as an increasingly important issue for modern integrated circuits. Thinner gate oxides, complex chips with multiple power supplies and/or mixed-signal blocks, larger chip capacitance and faster circuit operation all contribute to increased ESD-sensitivity of advanced semiconductor products [1]. Detailed understanding of complex circuit-devic...
The paper discusses the hardware and software security requirements in an embedded device that are involved in the transfer of secure digital data. The paper gives an overview on the security processes like encryption/decryption, key agreement, digital signatures and digital certificates that are used to achieve data protection during data transfer. The paper also discusses the security require...
according to IEC 61850 Klaus-Peter Brand, Wolfgang Wimmer Switzerland Summary The standard IEC 61850 „Communication Networks and Systems in Substations“ will provide interoperability for all functions in substations. To realize interoperable devices their data and functions have to be modeled according to IEC 61850. The approach and the data model of the standard is the key for understanding, b...
INTRODUCTION Current models for the endovascular treatment of aneurysms often require the use of adjuvant devices. Balloon-assisted techniques require temporary occlusion of the parent vessel. Intravascular stents require the use of antiplatelet medication. A novel device that achieves temporary neck protection without parent vessel occlusion or antiplatelet medication is examined in a canine m...
Surge protective device is a part of internal lightning protection and it crucially to divert the certain amount of surges to the ground before the protected load able to handle. Therefore, this paper studying the enhancement of SPD through the effect of adding a filter in hybrid surge protection circuit using simulation modeling. Ordinarily, filter is used as in eliminating noises in certain a...
This paper focuses on the behaviour of the cell capacitor discharge currents during DC faults in half-bridge modular multilevel converters. Active switches, not designed for fault conditions, are tripped to minimize discharge currents effect on the semiconductor switches. Two levels of device protection are commonly in place; driver level protection monitoring collector-emitter voltage and over...
Cyber attacks are continuing to hamper working of Internet services despite increased use of network security systems such as firewalls and Intrusion protection systems (IPS). Recent Distributed Denial of Service (DDoS) attacks on Dec 8, 2010 by Wikileak supporters on Visa and Master Card websites made headlines on prime news channels all over the world. Another famous DDoS attacks on Independe...
In this paper, a novel LVTSCR-based device for electrostatic discharge (ESD) protection of integrated circuits (ICs) is designed, fabricated and characterized. The proposed device is similar to the conventional LVTSCR but it has an embedded PMOSFET in the anode n-well to enhance the turn on speed, the clamping capability and the robustness. This is possible because the embedded PMOSFET provides...
