PW2330 develops a high efficiency synchronous step down DC-DC converter capable of delivering3A output current. PW2330 operates over a wide INPUT voltage range from 4.5V to 30V andintegrates main switch and synchronous switch with very low RDS(ON) to minimize the conductionloss. PW2330 adopts the proprietary instant PWM architecture to achieve fast transient responsesfor high step down applications and high efficiency at light loads. In addition, it operates atpseudo-constant frequency of 500kHz under continuous conduction mode to minimize the size ofinductor and capacitor

The PW2053 is a high-efficiency monolithic synchronous buck regulator using a constantfrequency, current mode architecture. The device is available in an adjustable version. Supply currentwith no load is 40uA and drops to <1uA in shutdown. The 2.5V to 5.5V INPUT voltage range makesthe PW2053 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provideslow dropout operation, extending battery life in portable systems. PWM/PFM mode operationprovides very low output ripple voltage for noise sensitive applications. Switching frequency isinternally set at 1.2MHz, allowing the use of small surface mount inductors and capacitors. Lowoutput voltages are easily supported with the 0.6V feedback reference voltage

PW1555 is a programmable current limit switch with INPUT voltage range selection and outputvoltage clamping. Extremely low RDS(ON) of the integrated protection N-channel FET helps toreduce power loss during the normal operation. Programmable soft-start time controls the slew rateof the output voltage during the start-up time. Independent enable control allows the complicatedsystem sequencing control. It integrates the over-temperature protection shutdown andautorecovery with hystersis

高清電子書-C++ Primer Plus, 第6版英文版 1438頁Learning C++ is an adventure of discovery, particularly because the language accommodates several programming paradigms, including object-oriented programming, generic programming, and the traditional procedural programming.The fifth edition of this book described the language as set forth in the ISO C++ standards, informally known as C++99 and C++03, or, sometimes as C++99/03. (The 2003 version was largely a technical correction to the 1999 standard and didn’t add any new features.) Since then, C++ continues to evolve.As this book is written, the international C++ Standards Committee has just approved a new version of the standard.This standard had the informal name of C++0x while in development, and now it will be known as C++11. Most contemporary compilers support C++99/03 quite well, and most of the examples in this book comply with that standard. But many features of the new standard already have appeared in some implementations, and this edition of C++ Primer Plus explores these new features. C++ Primer Plus discusses the basic C language and presents C++ features, making this book self-contained. It presents C++ fundamentals and illustrates them with short, to-the-point programs that are easy to copy and experiment with.You learn about INPUT/output (I/O), how to make programs perform repetitive tasks and make choices, the many ways to handle data, and how to use functions.You learn about the many features C++ has added to C, including the followi

5G通信系統中massive-MIMO-FBMC技術的結合概述摘要為了應對第五代移動通信（5G）中更高數據率和更低時延的需求，大規模MIMO （massive multiple-INPUT multiple-output）技術已經被提出并被廣泛研究。大規模 MIMO技術能大幅度地提升多用戶網絡的容量。而在5G中的帶寬研究方面，特別 是針對碎片頻譜和頻譜靈活性問題，現有的正交頻分多址（Orthogonal Frequency Division Multiplexing, OFDM）技術不可能應對未來的挑戰，新的波形方案需要 被設計出來。基于此，FBMC（filter bank multicarrier）技術由于具有比OFDM低 得多的帶外頻譜泄露而被受到重視，并已被標準推進組IMT-2020列為5G物理層 的主要備選方案之一。 本文首先回顧了5G中波形設計方案（主要是FBMC調制）和大規模多天線系 統（即massive MIMO）的現有工作和主要挑戰。然后，簡要介紹了基于Massive MIMO的FBMC系統中的自均衡性質，該性質可以用于減少系統所需的子載波數 目。同時，FBMC中的盲信道跟蹤性質可以用于消除massive MIMO系統中的導頻 污染問題。盡管如此，如何將FBMC技術應用于massive MIMO系統中的誤碼率、 計算復雜度、線性需求等方面仍然不明確，未來更多的研究工作需要在massive MIMO-FBMC方面展開來。 關鍵詞：大規模MIMO；FBMC；自均衡；導頻污染；盲均衡
