Title
Update on Pre-Distortion Techniques to Linearize Wireless Broadband Power Amplifiers
Speakers
Rajeev Krishnamoorthy, CTO of Scintera Networks
John Wood, Sr. Principal Member of Technical Staff, Maxim Labs
Abstract
Power amplifiers in wireless communication systems require high linearity and pre-distortion techniques are required to achieve this without compromising on power efficiency. For this meeting, we have two experts in the field of power amplifier linearization: Dr. John Wood will present an update on new developments in digital pre-distortion and Dr. Rajeev Krishamoorthy will talk about a novel analog pre-distortion technology operating on signals in the RF domain, which has been gaining traction in mid-to-low power cellular base stations as well as several other adjacent markets. Dr. Krishnamoorthy’s talk will also cover a family of RF Power Amplifier Linearizers (RFPAL) System-on-Chip (SoC) solutions from Scintera. Dr. Krishnamoorthy will also discuss the applicability of the underlying analog signal processing technology to other markets.

Title
Next Generation 100 Gigabit Ethernet, Low Power CMOS SerDes, and Signal Integrity Challenges
Speaker
Hamid Rategh, Inphi
Abstract
The continued rapid growth in multimedia and mobile traffic over the Internet is driving service providers and datacenter operators to adopt next generation 100 Gigabit Ethernet (100GbE) technology based upon IEEE 802.3ba 100GbE-LR4/ER4 standards. To meet this bandwidth demand, the industry must innovate to achieve high speed, low power, small form factor, and low cost that has been the hallmark of Ethernet technologies. We will discuss a new 100GbE architecture based upon low power CMOS SerDes technology and some of the challenges from signal integrity point of view to meet the higher bandwidth, lower power, higher port density, and lower cost requirements of such systems.
Biography
Hamid Rategh is currently Sr. director of Engineering at Inphi, where he leads the signal integrity efforts for the company’s 100G products. With more than 13 years of industry experience, Dr. Rategh has been responsible for development of wide range of products from RFICs to adaptive equalizers for optical communication and also Mixed-Signal Memory interface products.
Prior to joining Inphi Dr. Rategh was Sr. Director of Engineering at Scientera Networks where he was responsible for the development of adaptive Electronic Dispersion Compensation chips for 10GBASE-LRM using their proprietary analog signal processing technology. Dr. Rategh was also cofounder and VP of Engineering of Tavanza which was later acquired by Celeritek in 2002 and subsequently by Anadigics in 2003.
Dr. Rategh holds a Ph.D. degree in Electrical Engineering from Stanford University.

Title
New Architecture for Next Generation User-Centric Mobile Device
Speaker
Prof. Willie W. Lu, Chief Inventor of OWA Technology and Chairman of Technaut Intellectual Venture
Abstract
The wireless transmission theory tells us that no single wireless transmission technology can provide both broadband high-speed radio transmission and seamless fast mobility capability in a mobile fast-fading propagation model environment unless we reduce the mobile network capacity tremendously. Open Wireless Architecture (OWA) was proposed to balance the above requirements in commercial mobile communications with converged multiple air interfaces in a cost-effective and spectrum-efficient way.
Our research discovers that when the wireless transmission bandwidth is enough, the information processing consumes much more resources and energies than the transmission processing in the mobile device. If we can reduce the processing burdens in the mobile device including baseband signal processing, application processing and networking processing, the overall power consumption can be tremendously minimized and the terminal system can be simplified.
The OWA technology platform has secured enough transmission bandwidth by converging multiple wireless standards in one common platform so that the mobile device can be optimized for best-of-effort high-speed transmission.
By employing a computer server with an IP address as the Virtual Mobile Server, we can configure this server as the mobile cloud serve to handle the processing tasks for the mobile device which becomes the mobile cloud client accordingly.
The OWA mobile cloud architecture tremendously reduces the processing tasks in the mobile device by pushing much processing tasks remotely and synchronously to the virtual mobile server through IP connection based on OWA network access control. The OWA mobile device is open to various carriers selected and optimized by mobile user.
The OWA architecture also facilitates the next generation SIM system supporting multiple air interfaces and open OS virtual machine interface supporting multiple operating systems for the future mobile device.
This seminar relates to the next generation iPhone and Android smartphone evolutions, both in device systems and in wireless transmissions.
