文章/文档 It was proposed that perfect invisibility cloaks can be constructed for hiding objects from electrom
It was proposed that perfect invisibility cloaks can be constructed for hiding objects from electromagnetic
illumination (Pendry et al., Science 312, p. 1780). The cylindrical cloaks experimentally
demonstrated (Schurig et al., Science 314, p. 997) and theoretically proposed (Cai et al., Nat. Photon ...

书籍 MIMO+Wireless+Communications5
When we started thinking about writing this book, we had been working together for more
than five years on the borderline between propagation and signal processing.Therefore, it
is not surprising that this book deals with propagation models and design tools for MIMO
wirelesscommunications.Yet, thisb ...
书籍 RFIC+Design+for+Cognitive+Radio+Systems
Cognitive radios have become a vital solution that allows sharing of the scarce
frequency spectrum available for wireless systems. It has been demonstrated
that it can be used for future wireless systems as well as integrated into 4G/5G
wireless systems. Although there is a great amount of literatur ...

The main aim of this book is to present a unified, systematic description of
basic and advanced problems, methods and algorithms of the modern con-
trol theory considered as a foundation for the design of computer control
and management systems. The scope of the book differs considerably from
the to ...
技术资料 四阶级联Sigma-Delta转换器设计
·摘要:  在当今的DSP系统中,作为联系模拟世界与强大的数字领域的桥梁,ADC演了重要的角色.由于Sigma-Delta ADC很好地折衷了转换器的速度和精度,因此成为了用于通信系统中ADC的极佳选择.本文采用了2-1-1结构实现4阶调制器,设计了一个全差分增益提高Telescopic运算放大器,用于第一级积分器.采用了0.6μmN-Well CMOS工艺 ...
电源技术 简单、高效USB电源管理IC解决方案
 
Linear Technology offers a variety of devices that simplifyconverting power from a USB cable, but the LTC®3455represents the highest level of functional integration yet. The LTC3455 seamlessly manages power flowbetween an AC adapter, USB cable and Li-ion battery,while complying with U ...
单片机编程 基于HITAG读写芯片HTRC110的读写设备设计
Designing read/write device (RWD) units for industrial RF-Identification
applications is strongly facilitated by the NXP Semiconductors HITAG
Reader Chip HTRC110. All needed function blocks, like the antenna
driver, modulator demodulator and antenna diagnosis unit, are integrated
in the HTRC11 ...
可编程逻辑 XAPP708 -133MHz PCI-X到128MB DDR小型DIMM存储器桥
 
The Virtex-4 features, such as the programmable IDELAY and built-in FIFO support, simplifythe bridging of a high-speed, PCI-X core to large amounts of DDR-SDRAM memory. Onechallenge is meeting the PCI-X target initial latency specification. PCI-X Protocol Addendum tothe PCI Local Bus Spec ...
Java书籍 THIS is really two books in one: a tutorial and a reference manual for JDBC, the application program
THIS is really two books in one: a tutorial and a reference manual for JDBC, the application programming interface that makes it possible for programmers to access databases from Java. The goal is to be useful to a wide range of readers, from database novices to database experts. Therefore, we have ...
