In this paper the target is to study the write power of SRAM cell with dual-gate MOS.Earlier designed memories using single gate MOS faced the problem related with stray capacitance and leakage current which increase the write power dissipation with the shrinking MOS feature and the requirement of Low-power devices.CMOS scaling causes in low Vt(Threshold Voltage) and reduce oxide thickness.Reduction in high thickness at high bias voltage forced the electrons to tunnel through the gate.The proposed dual gate MOS cell present that this leakage current during write access decreased.Because the dual gate MOS requires less operating voltage.Hence,8-bit,32-bit & 64-bit SRAM cells are designed & their write power is analyzed with respect to single gate.

Key words:CMOS, Dual-Gate, Leakage Power, MOS, SRAM.

In this project, we present a fully integrated asynchronous step-down switched capacitor dc–dc conversion structure suitable for supporting ultra-low-power circuits commonly found in biomedical devices. The proposed converter uses a PI controller as the heart of the control circuitry to generate the drive signals. To minimize the switching losses, the controller scales the switching frequency of the drive signals according to the loading conditions. A total of 350 pF on-chip capacitance was implemented to support a maximum of 230- W load power. Experimental test results confirm the expectedfunctionality and performance of the proposed circuit.

AODV Is Source Initiated A Routing Protocol. AODV Protocols Are Different From Traditional Proactive Protocols Since In Proactive The Routing Mechanism Is Based On Periodic Updates This Leads To High Routing Overhead. The Key Goal In Designing This Protocol Is To Reduce Overhead. Routing Messages In AODV Can Be Divided Into Path Discovery And Path Maintenance Messages. Path Discovery Includes The Route Request (RREQ) And The Route Reply (RREP), While The Latter Includes Route Error (RERR) And Hello Message. In AODV No Routing Structure Is Created Prior.

Simplified Active NPC (ANPC) Inverters Enable A Substantially Increased Output Power And An Improved Performance At Zero Speed For High-Power Electrical Drives. This Paper Analyzes The Operation Of Simplified ANPC Inverters Under Device Failure Conditions, And Proposes The Fault-Tolerant Strategies To Enable Continuous Operating Of The Inverters And Drive Systems Under Single Device Open- And Short-Failure Conditions. Therefore, The Reliability And Robustness Of The Electrical Drives Are Greatly Improved. Moreover, the Proposed Solution Adds No Additional Components To standard ANPC Inverters; Thus, The Cost For Robust Operation Of Drives Is Lower. Simulation Results Are Provided For Verification. Furthermore, A Comprehensive Comparison For The Reliability Function Of ANPC And NPC Inverters Is Presented. The Results Show That ANPC Inverters Have Higher Reliability Than NPC Inverters. Two Inverters Have Similar Reliability For Device Open Failure, While ANPC Inverters Have Higher Reliability Than NPC Inverters For Device Short Failure. Therefore The Input Voltage Is Renewable Energy And Is Rectified To DC Using Rectifier Circuit And Stored In The Battery.

This paper revises the study of computational complexity of solving the simultaneous equations. An equation is an expression of the form W1.W2.........Wk=id where each Wi is a variable with operator and id is the identity element. A solution to such an equation is the assignment of variables which realizes the equality. A system of equations is a collection of such equations; a solution is the assignment of values to unknown variables which simultaneously realizes each equation. We show that the problem of determining the solution is NP. The system of simultaneous equations is probably one of the most important topics in modern engineering computations. The paper examines the Methods of solving the Simultaneous Equations. Section 1 presents introduction. Section 2 discusses the Simultaneous Equations solution as NP. Section 3 describes Method of solving Simultaneous equations in detail. Section 4 Concludes.

Besides devastation, an earthquake also caused trauma and distress to many people who experience it. Due to that fact, the ruined housing area needs reconstruction, which is not only to build, but also to restore the "lives" in it. An interesting study in architecture field had been conducted in Bantul village, Yogyakarta, Indonesia, where all victims of the earthquake, without any background of formal education in engineering, had roles in reconstructing their devastated settlements after the earthquake. They did this only by holding into the mutual spirit to rise and restore their lives as soon as possible. The participation of Ngibikan Bantul village community after the earthquake had been written in history as a part of completing the rehabilitation and reconstruction of the housing after an earthquake.This study will discuss about things related to the success of that participatory reconstruction. Both roles and involvement of the builders, the rebuilding process, physical products of the process, and its impact for community's social life and the general communities. The explanations will refer to the pattern of community participatory in the rebuilding process after the earthquake.
