The use of optical free-space emissions to provide indoor wireless commu-
nications has been studied extensively since the pioneering work of Gfeller
and Bapst in 1979 [1]. These studies have been invariably interdisciplinary in-

学术论文 LOBS边缘节点突发包组装和光板FPGA实现
近年来提出的光突发交换OBS(Optical．Burst Switching)技术，结合了光路交换(OCS)与光分组交换(OPS)的优点，有效支持高突发、高速率的多种业务，成为目前研究的热点和前沿。 本论文围绕国家“863”计划资助课题“光突发交换关键技术和试验系统”，主要涉及两个方面：LOBS边缘节点核心板和光板FPGA的实现方案，重点关注于边 ...
学术论文 板级光互连协议研究与FPGA实现
随着集成电路频率的提高和多核时代的到来，传统的高速电互连技术面临着越来越严重的瓶颈问题，而高速下的光互连具有电互连无法比拟的优势，成为未来电互连的理想替代者，也成为科学研究的热点问题。目前，由OIF(Optical Intemetworking Forum，光网络论坛)论坛提出的甚短距离光互连协议，主要面向主干网，其延迟、功耗、兼 ...
模拟电子 校准ADC内部偏移的光学微控制器DS4830
Abstract: The DS4830 optical microcontroller's analog-to-digital converter (ADC) offset can change with temperature and gainselection. However, the DS4830 allows users to measure the ADC internal offset. The measured ADC offset is added to the ADCoffset register to nullify the offset error. Th ...

AVALANCHE PHOTODIODE BIAS SUPPLY 1Provides an output voltage of 0V to +80V for reverse biasingan avalanche photodiode to control its gain. This circuit canalso be reconfigured to supply a 0V to –80V output.LINEAR TEC DRIVER–1This is a bridge-tied load (BTL) linea ...
电源技术 DN384 精确的电源排序,防止系统损坏
 
Many complex systems—such as telecom equipment,memory modules, optical systems, networking equipment,servers and base stations—use FPGAs and otherdigital ICs that require multiple voltage rails that muststart up and shut down in a specific order, otherwise theICs can be damage ...
电源技术 DN436微型全桥压电马达驱动器
 
Piezoelectric motors are used in digital cameras for autofocus,zooming and optical image stabilization. Theyare relatively small, lightweight and effi cient, but theyalso require a complicated driving scheme. Traditionally,this challenge has been met with the use ofseparatecircuits, inclu ...
电源技术 雪崩光电二极管的偏置电压和电流检测电路
 
Avalanche photodiodes (APDs) are widely utilized in laserbased fiberoptic systems to convert optical data intoelectrical form. The APD is usually packaged with a signalconditioning amplifier in a small module. An APD receivermodule and attendant circuitry appears in Figure 1. TheAPD modul ...
电源技术 光纤激光器的电流源分析
 
A large group of fiber optic lasers are powered by DCcurrent. Laser drive is supplied by a current source withmodulation added further along the signal path. Thecurrent source, although conceptually simple, constitutesan extraordinarily tricky design problem. There are anumber of practica ...
