Taras Dudar and Chris Maxwell Texas Instruments (1) HDD Preamplifiers, and (2) Electrostatic Discharge Protection With the growth in electronics market, the number of applications that uses memory devices is increasing every year. Nowadays hard disk drives (HDD) are an essential part of not only computers but also applications such as IPODs, TIVO's and many other new gadgets entering the market every day. Stiff competition from the flash memory devices puts high pressure on the capacity and performance of the hard disk drives. This translates into stringent requirements on the HDD preamplifiers. This presentation covers the basics functions and challenges of the various blocks which make the HDD preamp. Electrostatic Discharge (ESD) protection has become a major challenge for integrated circuit (IC) designers as customer requirements have increased along with circuit sensitivities owing to ever-smaller geometries. This talk intends to familiarize the viewer with the various forms of ESD along with testing techniques for each. It will also contrast ESD with electrical overstress (EOS) both in terms of definition as well as observed IC damage. Finally, various on-chip as well as system-level protection methodologies will be explored. Biography: Taras Dudar received the M.S. in electrical engineering from National Technical University of Ukraine - Kiev Polytechnic Institute in May of 1999 and M.S in electrical engineering from Oregon State University in Dec 2002. He joined the Storage Products Group of Texas Instruments as a mixed-signal design engineer responsible for the research and design of numerous analog front-ends for high performance preamplifier and read channel communication circuits for the hard disk drive industry. The main focus of his efforts has concentrated on preamp architecture design for desktop applications which involves high speed line drivers, low noise wide band amplifiers and also fault and measurement circuitry. He has been involved with digital as well as BiCMOS analog design in the process. He has led numerous successful projects and has been very involved in product definition with multiple customers as well as industry standards definition. Chris Maxwell is an analog/mixed signal design manager at TI. He has been with TI since 1994 where he started as a college co-op in Product Engineering and was elected to TI's technical staff in 1999. In 2000, he transferred into circuit design and was promoted to Senior Member Technical Staff in 2004. Chris has two patents and a number of technical articles and applications notes to his name. He was recognized as a "Modern Day Technology Leader" at this year's Black Engineer of Year Awards which recognizes women and men who are shaping the future of engineering, science and technology.
