  The Fujitsu ASIC Platform: Combining Engineering Expertise with Best-in-Class Tools and Process Technology to Deliver Cost-Efficient Custom Silicon

  Advanced ASIC (Application Specific IC) development today requires complex and expensive design tools, process technologies, and engineering teams. Some large companies can commit the resources needed for the complete tool chain and design flow, all the way from circuit design to Graphic Data Systems (GDS) and beyond. This option, using a flow known as Customer Owned Tooling (COT), is a good choice for companies that can amortize costs over many products that are manufactured in high volumes for broad markets.

  Motivation for RF Integration

  While CMOS technology has made great strides in its ability to fabricate radio frequency (RF) circuitry, many RF chip designers have yet to take advantage of this capability. After long relying on more expensive technologies such as silicon germanium (SiGe) and gallium arsenide (GaAs), RF designers who transition to the latest RF CMOS processes gain the enormous advantages of full system-on-a-chip (SoC) integration.

  High-Performance / Low-Power 65nm CMOS Technology CS200 / CS200A

  This paper describes Fujitsu's CS200/CS200A series 65nm CMOS technology with a focus on the technology's improved performance and low power consumption. These advantages result from the technology's ability to achieve more than twice the density of transistor packing compared to 90nm technology as well as Fujitsu's advanced copper and ultra-low-k material (ULK) technology. The ULK material serves as an inter-level dielectric that reduces parasitic interconnect capacitance compared to previous technologies and thus significantly improves speed and power characteristics. The paper also describes Fujitsu's wide range of packaging choices and rich IP portfolio for use with the CS200/CS200A technology.

  Beamforming Boosts the Range and Capacity of WiMAX Networks

  Having gained tremendous momentum over a number of years, WiMAX is now widely viewed as a leading candidate for fourth-generation (4G) wireless data communication. Because WiMAX is based on Internet Protocol (IP), the technology builds on principles that have proven versatile and cost-effective in the Internet. Compared to traditional 3G cellular networks, WiMAX offers a more affordable technology for transferring large amounts of data with high throughput.
  
  A technology known as adaptive beamforming can magnify this WiMAX advantage considerably. At a relatively low implementation cost, beamforming improves both the range and capacity of a WiMAX network. In fact, beamforming reduces capital and operating expenses for WiMAX implementations by minimizing the number of base stations needed in a network.
