This book introduces a Gate Diffusion Input (GDI) methodology as an alternative approach in digital circuits. In this technique, a wide range of complex logic functions can be realized by using a lower number of CMOS transistors. The advantages of using GDI technique are multi-folded. The first is to implement digital gates (i.e. inverters, NAND, NOR, XOR, XNOR, buffers, etc.) with very low propagation delay and high logic level swing. As a second advantage, the GDI-based circuits consume lower power consumption and chip area compared with the CMOS equivalent. This provides a new implementation of digital circuits which are suitable for longer-lasting portable devices, like smartphones, tablets, IoT, etc.. A third advantage is the simplicity of circuit design by using very small cell library. In this book, after a brief review of GDI specifications, we will discuss different architectures of GDI-based digital circuits that have been recently proposed.
In this thesis work, a new technique for designing logic circuits called the Modified Gate Diffusion Input (MGDI) logic is discussed. This logic is adopted from the Gate Diffusion Input (GDI) technique. GDI was first proposed in the year 2002 for solving the problems associated with different CMOS logic styles. GDI cell can be used to implement wide variety of complex logic functions using only two transistors. GDI technique allows design of high speed and low power circuits with reduced number of transistors as compared to static CMOS and Pass Transistor Logic (PTL) techniques. This work aims to design a various high performance adders and multipliers.
High Quality Content by WIKIPEDIA articles! The Mitsubishi SUW (Smart Utility Wagon) is a series of concept cars sharing a common design theme, and first exhibited by Japanese automaker Mitsubishi Motors at the 1999 Frankfurt and Tokyo Motor Shows. The Smart Utility Wagon theme was introduced late in 1998 as a demonstration of the company's corporate slogan of the time, "Innovation in Motion", which was itself to represent "smart design" and "ecology conscious[ness]". Specifically, SUWs shared the company's gasoline direct injection (GDI) engine technology, a taller roofline for easier entry and exit, and interior space competitive with larger vehicles. The three individual vehicles Mitsubishi produced were the SUW Advance, a five door hatchback family car, the SUW Compact a three door hatchback small car, and the SUW Active sport utility vehicle.
As technology scales into the nanometer regime leakage current, active power, delay and area are the important metric for the analysis and design of complex arithmetic logic circuits. In this paper, low leakage 1bit full adder cell are proposed for mobile applications and a novel technique has been introduced with improved staggered phase damping technique and also Gated Diffusion Input (GDI) technique for further reduction in the Active power. Leakage power is being estimated when the circuits are connected with a sleep transistor, Further compared to the Base case and Design1 and Design2 and GDI Technique when a circuit is connected to sleep transistor. We introduced a new transistor resizing approach for 1bit full adder cells to determine the optimal sleep transistor size which reduce the leakage power and Area. The simulation results depicts that the proposed design also leads to efficient 1bit full adder cells in terms of standby leakage power, active power. We have performed simulations using Microwind 90nm standard CMOS technology at room temperature with supply voltage of 1V.
This book presents design of a low power high speed 1-bit ALU in 45nm CMOS technology. Low power high speed circuit design has emerged as a challenging and an emerging field among circuit designers and researchers. A 1-bit ALU is designed in 45nm CMOS technology by using CMOS, nMOS PTL and GDI circuit techniques and its performance characteristics such as power dissipation, delay, power-delay product and number of transistors are compared. GDI technique provides better performance characteristics for designing a low power high speed VLSI circuit. This circuit technique reduces power dissipation, delay, and it also maintains low complexity in the integrated circuit design. This technique is suitable for designing a low power high speed VLSI circuit by using very less number of transistors as compared to other circuit design techniques. This technique has emerged as an effective circuit technique for designing a low power high speed VLSI circuit. The contributions made in this book would help circuit designers and researchers in designing low power high speed integrated circuits.
Progressive reductions in vehicle emission requirements have forced the automotive industry to invest in research and development of alternative control strategies. Continual control action exerted by a dedicated electronic control unit ensures that best performance in terms of pollutant emissions and power density is married with driveability and diagnostics. Gasoline direct injection (GDI) engine technology is a way to attain these goals.This brief describes the functioning of a GDI engine equipped with a common rail (CR) system, and the devices necessary to run test-bench experiments in detail. The text should prove instructive to researchers in engine control and students are recommended to this brief as their first approach to this technology. Later chapters of the brief relate an innovative strategy designed to assist with the engine management system, injection pressure regulation for fuel pressure stabilization in the CR fuel line is proposed and validated by experiment. The resulting control scheme is composed of a feedback integral action and a static model-based feed-forward action, the gains of which are scheduled as a function of fundamental plant parameters. The tuning of closed-loop performance is supported by an analysis of the phase-margin and the sensitivity function. Experimental results confirm the effectiveness of the control algorithm in regulating the mean-value rail pressure independently from engine working conditions (engine speed and time of injection) with limited design effort.

IN THE PAST FEW MONTHS, a deluge of .NET books has hit store shelves, each one eager to explain the new programming philosophy of the .NET world. In the excitement, many of these books have left out the tricks and insights needed to really master .NET programming. Part of the problem is that no single work can cover the entire .NET platform-a sprawling, ambitious framework that revolutionizes everything from Internet applications to data access technology. Many .NET books provide a good overview of essential concepts, but they can't deal with the subtleties needed for all types of development. This book represents the start of the second wave of .NET books: closely focused works that give you the insight of experienced developers about a single aspect of .NET programming. User Interfaces in VB .NET: Windows Forms and Custom Controls takes a close look at all the ingredients you can use to design state-of-the-art application interfaces. It also delves into entirely new topics like custom-control design and GDI+, the next -generation painting framework for Wmdows. You won't just learn about anchoring and docking, you'll work with examples that show document view architecture, custom -control layout engines, dockable windows, and hit testing with owner-drawn controls. You also learn how to design irregularly shaped forms, unshackle data binding, and build an integrated help system.
