教程资料 为您的FPGA选择合适的电源
Abstract: There are many things to consider when designing a power supply for a field-programmablegate array (FPGA). These include (but are not limited to) the high number of voltage rails, and thediffering requirements for both sequencing/tracking and the voltage ripple limits. This application n ...
开关电源 DN492-双单片降压集成温度监控模块
 
Multioutput monolithic regulators are easy to use and fi tinto spaces where multichip solutions cannot. Nevertheless,the popularity of multioutput regulators is temperedby a lack of options for input voltages above 30V andsupport of high output currents. The LT3692A fi lls thisgap with a ...

sim 文件系统In addition, its quality of service reduces because of reliance on traditional circuit-switched network elements. At that former time, people hoped to build a based system, which could access a centralized server network, would always have access to the latest traffic information and cou ...
文章/文档 In an electromagnetic cloak based on a transformation approach, reduced sets of material properties
In an electromagnetic cloak based on a transformation approach, reduced sets of
material properties are generally favored due to their easier implementation in reality,
although a seemingly inevitable drawback of undesired reflection exists in such cloaks.
Here we suggest using high-order transforma ...

The FPGA can realize a more optimized Digital controller in DC/DC Converters when compare to DSPs. In this paper, based on the FPGA platform, The theoretical analysis, characteristics, simulation and design consideration are given. The methods to implement the digital DC/DC Converters have been rese ...
书籍 Complex Orthogonal Space-Time Processing
Multiple-Input Multiple-Output (MIMO) systems have recently been the
subject of intensive consideration in modem wireless communications as they
offer the potential of providing high capacity, thus unleashing a wide range of
applications in the wireless domain. The main feature of MIMO systems is th ...
书籍 GNSS+Receivers+for+Weak+Signals
Many applications have required the positioning accuracy of a Global Navigation
Satellite System (GNSS). Some applications exist in environments that attenuate
GNSS signals, and, consequently, the received GNSS signals become very weak.
Examplesofsuchapplicationsarewirelessdevicepositioning,position ...

技术资料 基于三层架构的RFID接口模型的研究与应用
随着自动识别技术的快速发展，RFID凭借其特殊的技术优势被广泛应用于工业、商业和交通运输等领域。本文首先介绍了RFID的发展与现状，研究了RFID的工作原理和RFID接口软件技术，在分析传统RFID接口模型的基础上，参考EPC标准体系，提出了一种基于三层架构的RFID系统接口模型的设计方案。与其它接口模型相比，该模型支持Web应 ...
单片机编程 8-bit I2C-bus and SMBus IO port with reset
The PCA9557 is a silicon CMOS circuit which provides parallel input/output expansion for
SMBus and I2C-bus applications. The PCA9557 consists of an 8-bit input port register,
8-bit output port register, and an I2C-bus/SMBus interface. It has low current consumption
and a high-impedance open-dra ...
