Bryan Bloodworth Distinguished Member Technical Staff SPG/Preamp Design Branch Manager Texas Instruments Incorporated >From Multi-Gb/s RAID Servers to Ultra Low-Power iPods: Analog Front-End Circuit Design Techniques for the HDD Industry Analog system-on-chip (ASOC) design techniques are presented as they pertain to hard disk-drive (HDD) preamplifiers. Specifically, an overview of the preamplifier ASOC is detailed and the specific techniques used in high-performance inductive line drivers used in server-class HDDs are compared to techniques used in ultra-low power (ULP) portable MP3, iPod, and MPEG applications. Biography: Bryan E. Bloodworth received the B.S. in electrical engineering from Washington State University in May of 1995. He then 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 have concentrated on wide-band SiGe and BiCMOS multipliers, amplifiers, and AGC circuits integrated into large analog systems-on-chip (ASOC). In 2000, Mr. Bloodworth was elected as a Member of TI's technical community and later as a Senior Member in 2002. He is currently TI's Dallas Design Branch Manger responsible for the development of mobile & desktop preamplifier ASOCs and is a Distinguished Member of the Technical Staff. He holds sixteen patents with several additional patents pending and is responsible for setting many industry-leading standards.
