Leading Trends

Holographic Data Storage to Help Make Terabyte Discs a Reality.  .  .  p. 51
Holographic recording is gaining attention like never before as a technology with strong potential for realizing 200GB to 1TB optical discs. 
At “ISOM/ODS 2005,” the international symposium on technology relating to optical data storage held in July 2005, two major developments were made towards the practical application of holographic recording.

Search Engines Look to Engulf Maps.  .  .  p. 61
One after the other, leading Internet search engines are launching geographical information services that make use of maps and satellite images.  This trend is set to have an influence not only on personal computers, but also on mobile phones and car navigation systems.

Power Supplies Will Also Be on a Chip.  .  .  p. 81
Power supply voltage is steadily decreasing as LSI become smaller and smaller.  Designing circuits with a low power supply voltage of +1V is problematic.  Unexpected voltage fluctuations, which affect normal LSI operation, are a growing hindrance in design.  How can this be overcome?  If the distance between power supply circuit and LSI can be reduced, the fluctuations can be brought under control.  In time, the power supply circuits can be incorporated into the chip.

Developing a 10 bit, 125 Megasample-Per-Second 40mW Pipeline Type A-D Converter .  .  .  p. 111
Fujitsu Laboratories Ltd. has developed circuit architecture for system LSI in digital home appliances that can lower the level of power consumed by pipeline analog-to-digital converters (ADCs). 
The idea was not to employ the ordinary sample and hold circuits found in conventional architecture.  When the new architecture was tried for the fabrication of a 10-bit resolution ADC, power consumption dropped by 25 percent compared with the input front-end circuit of a similar conventional ADC, while maintaining the same noise characteristics. 
This could contribute greatly to a reduction of power consumption in system LSI for digital television receivers and communication devices.  In this article, the developers explain the new ADC architecture in detail along with the noise and other basic characteristics of their prototype ADC.

Lineup of 16 - 24 bit High Resolving ΔΣA-D Converters with Power and Cost Advantages.  .  .  p. 120
In electronic devices that deal with digital signals, the analog-to-digital converter (ADC) is a component that converts all the analog signals present into digital signals.  There are a number of different methods that an ADC can use to convert the analog signals, but here we are going to look at a chip with built-in delta sigma analog-to-digital conversion.
There are many types of ADCs with differing resolutions and sampling rates (conversion rates).  An incorrect selection could mean a desired resolution is not achieved or unnecessary power consumption and costs are generated. Delta sigma ADCs achieve high resolutions more easily than other types and are characterized by their low power consumption and low price.  Demand for these converters is growing as digital recording functions, their strong point, are being incorporated into a greater number of devices.  They are also increasingly becoming mainstream in industrial applications.

Method for Practically Formatting LDPC Code.  .  .  p. 126
Low density parity check (LDPC) codes possess a high error correction capability, which means they have the potential to become the standard error correcting code for next-generation communication standards targeting ultra high-speed data transmission, and for high-density recording devices. 
The first installment in this series explains LDPC code fundamentals and their definition method, using graphs.

The Real Threat of “Side Channel Analysis” (Final) .  .  .  p. 131
The previous two installments introduced the methods for side channel analysis and industry trends. 
This final installment explains techniques for defending against side channel analysis and methods for evaluating those techniques.  There are several defense methods, but the one that is currently the most researched is called the “artistic” method.

Digital RF Technology Will be the Mainstream for Radio Circuitry.  .  .  p. 140
Digital RF technology, which substantiates RF circuits of wireless terminals through digital processing, is spreading.  As the circuits are manufactured using CMOS technology, it is easier to integrate them with other digital circuits on the same chip. 
Texas Instruments Inc, which is leading the way in the application of this technology, explains here about the background to technological development and future prospects.
