Dean A. Richard Newton Ucumulative Price-Performance Advances In Dean A. Richard Newton u Cumulative price-performance advances in technologies are bringing ICT within reach of the global poor u Emergence of successful business models has spurred commercial interest in these unconventional but large markets u Many successful pilot applications have demonstrated the positive impact of ICT on global sustainability and quality-of-life uAnd many of the very best ICT researchers from throughout the world are passionate about this challenge! Dean Richard Newton [email protected] Page 1 BREWER’S CONJECTURE: Providing traditional enabling infrastructure, like building out roads, rail, the electrical grid and providing piped water is very expensive and can only really be economically justified for high density, relatively affluent communities. Network infrastructure, on the other hand, is inexpensive enough to deploy economically to rural areas and can be used to build the economic base that then justifies investing in roads, rail, electricity and water grids later.

  • How to Drive Gan Enhancement Mode Power Switching Transistors
    APPLICATION NOTE How to Drive GaN Enhancement Mode Power Switching Transistors This application note sets out design guidelines and circuit layout considerations for the gate drive of GaN Systems enhancement mode power switching transistors. The first section covers basic principles and the following section shows a specific design example. 1. Principles of driver design Gate characteristics Drain The equivalent gate circuit of a typical GaN Systems enhancement mode HEMT (E-HEMT) is shown in Figure 1. The model consists of two CGD capacitors (CGS and CGD), and an internal gate resistor RG,int. Full enhancement of the channel Gate RG,int requires VGS = 7V and the absolute maximum VGS limit of VGS is +/-10V. Excessive inductance in the CGS gate loop can drive the voltage beyond the rated maximum, which must be avoided. As the Source inductance increases, so does the ringing and peak Figure 1: Gate equivalent circuit voltage. Compared to a Si MOSFET with similar size (on-state resistance), GaN systems E- HEMTs have: a) Lower specified and peak gate voltage ratings, so a gate driver that is compatible with lower gate voltage operation is needed. b) Much lower gate capacitance, meaning that the external gate resistor will typically have a much higher value. Combined with lower gate voltage, this also means significant lower gate drive power loss thus smaller and lower cost gate driver can be used. For example, GaN E-HEMT GS66508P has gate drive power loss about 17 times lower than state of art superjunction MOSFET (Coolmos IPP65R065C7) with equivalent Rds(on). c) Lower transconductance, meaning that the gate should be driven close to the specified value, otherwise conduction losses will increase at higher currents.

  • Asics... the Website
    Last Edited by SP 14112004 INTRODUCTION TO ASICs An ASIC (pronounced a-sick; bold typeface defines a new term) is an application-specific integrated circuit at least that is what the acronym stands for. Before we answer the question of what that means we first look at the evolution of the silicon chip or integrated circuit ( IC ). Figure 1.1(a) shows an IC package (this is a pin-grid array, or PGA, shown upside down; the pins will go through holes in a printed-circuit board). People often call the package a chip, but, as you can see in Figure 1.1(b), the silicon chip itself (more properly called a die ) is mounted in the cavity under the sealed lid. A PGA package is usually made from a ceramic material, but plastic packages are also common. FIGURE 1.1 An integrated circuit (IC). (a) A pin-grid array (PGA) package. (b) The silicon die or chip is under the package lid. The physical size of a silicon die varies from a few millimeters on a side to over 1 inch on a side, but instead we often measure the size of an IC by the number of logic gates or the number of transistors that the IC contains. As a unit of measure a gate equivalent corresponds to a two-input NAND gate (a circuit that performs the logic function, F = A " B ). Often we just use the term gates instead of gate equivalents when we are measuring chip sizenot to be confused with the gate terminal of a transistor.

Most technological systems involve making more complicated decisions: for example, sorting out bottles into different sizes, deciding whether a room has a burglar in it or not, or knowing when to turn a central heating system on or off.

  • Equation Defined Device Modelling of Floating Gate Mosfets
    Equation Defined Device Modelling of Floating Gate M.O.S.F.E.Ts. ! M.CULLINAN Ph.D. Thesis 2015 LONDON METROPOLITAN UNIVERSITY Abstract This research work covers the development of a novel compact model for a Floating Gate nMOSFET that will be added to the QUCS library. QUCS (Quite Universal Circuit Simulator) is a GPL simulation software package that was created in 2006 and is continuing to develop and evolve, and there is already a substantial library of components, devices and circuits. Fundamentally, a floating gate device is an analogue device, even though modern technology uses it mainly as a non-volatile memory element there are numerous uses for it as an analogue device. A study has been carried out with regards to the principles of the physical phenomenon of charge transfer through silicon dioxide to a floating gate. The study has concentrated on the physical properties of the fabricated device and the principles of charge transfer through an oxide layer by Fowler–Nordheim principles. The EKV2.6 MOSFET was used as the fundamental device for the model that has been adapted by the addition of the floating gate. An equivalent circuit of an FGMOSFET was developed and analysed theoretically. This was then formulated into the QUCs environment and created as a compact model. Simulations were carried out and the results analysed to compare with the theoretical expectations and previous research works. It is well documented that the creation of equivalent circuits for floating gate devices is complicated by the fact that the floating gate is isolated as a node and as such cannot be directly analysed by simulators.
