...charge and interface trapping charge find an equivalent negative charge to result in the semiconductor band bending. So it is necessary to add the negative charge between metal and the semiconductor to let it become the flat band. It explains how the trapping charge to affect the threshold voltage illustrated by figure 6. [14] Figure 5.C-V shows the relationship between the impact of radiation for Vt[14] Figure 6.The C-V curves for the PMOS devices with POLY SI irradiated [14] 2.4.2.Interface-trap capacitance effects Oxide trapping tends to cause the shift for the threshold voltage while the interface trapping is likely to result in the larger sub-threshold slope to decrease the speed of switching for transistors illustrated by figure 2. MOS device is a kind of capacitor, its metal gate and Si-substrate like the upper and lower plates of the capacitor. The oxide layer is a dielectric material between the plates, so when we calculate the value of MOS capacitor, the trapping charge is often ignored. In the real situation, trapping charge does exist while the interface-trapped charge is the most important impact particularly. The interface trapping charge will cause an interface-trap capacitance. [12] Interface trapped capacitance is connected silicon capacitors in the series. Thus, the value of capacitance for MOS component can be decreased significantly to lead to an increase of equivalent oxide thickness. In order to make device better capacitor characteristics, the density...

...There are so many devices on the market these days that it can be hard to make a decision when making a new purchase. One big topic these days is whether a laptop or a Chromebook is the better purchase. It turns out that they are both great products, and that the better purchase depends on the needs of the user. Many Chromebooks are less expensive, but I chose to compare a Chromebook and a laptop that are of similar price ranges. Using the Amazon, Toshiba and HP websites, I chose to compare a Toshiba Satellite C55 and a HP Chromebook 14. These two devices have similarities, but they are also very different. A laptop is a personal computer that is easily used on the go, as they are light and compact. These devices are designed to have the functionality of a desktop computer. Most applications and documents associated with the device are stored in the local memory. Therefore they can be used while connected or disconnected to the internet (gcflearnfree.org). A Chromebook is a different kind of laptop that runs on Google Chrome OS. They were designed to be used while connected to the internet therefore most of the applications and documents associated with the device are stored in the cloud (laptopmag.com). Both devices have high definition Intel graphics along with 1366 x 768 high definition LED backlit displays. Their audio and webcam specifications are almost equivalent. The only audio difference is that the Chromebook’s microphone has echo cancellation and noise reduction...

...Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it. Bluetooth is a wireless technology standard used for transmitting data over short distances. The transmitter designed for the paper is a Bluetooth based transmitter for voice signal transmission and a similar transmitter for video transmission except for Analog to Digital Converter which is replaced by an Image Processing System. The Bluetooth runs at license exempt band of 2.45 Gigahertz and within a range of 10 meters. The older versions were providing speeds of about 2.1 Mbps. But the modern Bluetooth version 4.1 provides improved speeds for easy transmission, reduced buffering and less power consumption. The color depth of grayscale image used here is 8 bits and that of the Binary image is 1 bit monochrome. The multiplexer used here has a bandwidth of...

...Exercise One Nt1310 Week 1 In: Computers and Technology Exercise One Nt1310 Week 1 NT1310:Week 1 Telecommunications By: Kenneth Martin You are an IT Network Specialist and are required to develop the design of the company’s telephone system for its new building which will begin construction in a few months. In order to get a background which will help when developing the new system, your supervisor asked you to research the current Plain Old Telephone Service (POTS) currently used by the company. You must research the system components and report back to your supervisor , the Telecommunications Manager, within a week. 1. Describe a local land line phone system based on the following Landline Telephone Components: a. Local Loop a local loop is the wired connection from a telephone company's central office in a locality to its customers' telephones at homes and businesses. This connection is usually on a pair of copper wires called twisted pair. The system was originally designed for voice transmission only using analog transmission technology on a single voice channel. Today, your computer's modem makes the conversion between analog signals and digital signals. With Integrated Services Digital Network (ISDN) or Digital Subscriber Line (DSL), the local loop can carry digital signals directly and at a much higher bandwidth than they do for voice only. b. Central Office In telephone communication in the United States, a central office (CO) is an office in a locality...

You may have an opportunity to serve your community or work for a local employer for a project that will take between 20 and 30 hours. Project Logistics Career Services will identify an employer with needs in the following areas: Network related tasks (mostly confined to the LAN and Microsoft Windows Server 2008 environments) Students are expected to practice various skills discussed in all the technical courses in Quarters 1 through 3 of the NSA program at an employer’s site on network related tasks (more confined to the LAN and Microsoft Windows Networking with Server 2008 environments) that would involve installation, configuration, testing, maintenance and documentation of the worksite network and its components, and to properly document the technical information in all involved activities. Such documentation will be used as the source material for Items 2 and 3 defined in the Deliverables section of this document. Possible example projects could...

...important to be aware of what servers are Global Catalog servers, especially if you have more than one domain and even if only one domain, they will be prefered by applications like Exchange server. It is recommended to place the forest roles on one Domain Controller (DC) and the domain roles on another server. If not all Domain Controllers are Global Catalog servers, it is also important to place the infrastructure master on a server that is NOT a Global Catalog server. Recommended Best Practice setup of FSMO roles. Domain Controller #1 Place the two forest roles on this server. * Schema Master * Domain Master Domain Controller #2 Place the domain roles on this server. * RID Master * Infrastructure Master * PDC Emulator If more domains exist in the forest, place the domain roles on a server in theese domains like Domain Controller #2 Global Catalog configuration. In Windows 2008 Active Directory all Domain Controllers are by default Global Catalog servers, personally...
