Bringing the Millimeter-Wave Technology to the Home
Realizing gigabit-order wireless communication with just one transceiver circuit-milliwave communication is the ultimate wireless technology, enabling adequate transmission of HDTV baseband signals without having to compress them. Thanks to advances in miniaturization, CMOS (complementary metal oxide semiconductors) have milliwaves within range. Distinguished Japanese and foreign universities and research bodies of semiconductor manufacturers engaged in research into RF CMOS technology are starting to get serious about related development.

Making Inroads into Intel's Stronghold, AMD Increases Its Strength in the x86 Market
Advanced Micro Devices, Inc. (AMD) fought an uphill battle in the x86 microprocessor market for many years, but the company now has a spring in its step. It has caught up with Intel Corp. in terms of retail market share in the US and is taking full advantage of its acquisition of major Canadian graphics LSI supplier, ATI Technologies Inc. Underlying this strength is a change in the company's design philosophy made in mid 1990s.
Flash Memory-The Meaning of the Lawsuit over Invention versus Value
A settlement has been reached in a lawsuit in which former Toshiba Corp. engineer, Fujio Masuoka, was claiming compensation from that company for flash memories he had invented. What effect has the case had on electronics engineers and corporations?
Increasing the Light Emission Effectiveness of Green Light LEDs by Reformation of GaN Crystals
Green light-emitting diodes (LEDs) are employed as light sources for LCD televisions and LED displays. Research into new methods for manufacturing the LEDs is starting to heat up as players seek to raise luminous efficiency and output, which are lower compared to other LEDs.

Oscillators
Here we explain what to look for when choosing an oscillator, which are said to be found inside almost all electronic devices and are produced in volumes exceeding 10 billion units each year. The indicators to look at are oscillating frequency and accuracy in response to temperature changes. Ceramic oscillators are most used for comparatively low frequencies, such as microcontroller clock signals. For wireless communication and other high frequency applications requiring greater precision, crystal oscillators are often used. In the high frequency field, where fine adjustments need to be made with the oscillating circuit, oscillators with an integrated oscillating circuit become a popular choice. When designing your own oscillating circuit, you need to pay attention to the compatibility between semiconductor and oscillator. Mention must also be made of the growing interest in the application of silicon MEMS oscillators, samples of which have been shipped recently.

The Start of the IPTV Standardization Process (Part 1): The 4 Elements for Implementing a Service
Telecommunications technology standardization body, the International Telecommunication Union (ITU), has commenced work to standardize IPTV, which is the provision of broadcasting services along IP networks set up for communication purposes. In this series, Nippon Telegraph and Telephone Corp. (NTT) engineers participating in the IPTV standardization process explain in detail about four elements that will be necessary to realize an IPTV service.

The Latest on Quantum Encryption (Final): Transmitted Text Is Encrypted by Using Quantum Properties
This series has looked at quantum cryptography, a quantum key distribution technology that makes use of quantum properties to allow the secure sharing of keys between sender and receiver. The final installment introduces the Y-00 quantum protocol proposed in the year 2000. Y-00 uses the "quantum noise" property to securely deliver the communication data itself.
