PROFESSIONAL EXPERIENCE
Polar Semiconductor, Inc, Bloomington, MN October 2009- Sep 2011
Senior Applications Engineer
Applicatons / Systems engineer for design center launchiing innovative products into the Power Supply and LED driver markets.
Assisted customers with application problems and listened for profitable product ideas.
Created data sheets, white papers, app notes, design tools and marketing materiials as needed to extend and promote the product line.
ANALOG DEVICES INC, Wilmington, MA July 2004- Jan 2009
Senior Applications Engineer
Starting in applications support for ADI high speed comparator and ATE products, I provided circuit ideas, troubleshooting helpand practical advice on making circuits and high speed layouts that work.
Wrote data sheets and marketing presentation material whenever needed.
Analyzed the market, then wrote specs for a new family of comparators (ADCMP600-609) to compete for a maximum number of sockets with a minimum number of device types (10) using only package and metal variants. Acted as technical lead and mentor to the design and test team.
Moved from unofficial advisor into applications support of a family of clock buffers. The ADCLK905/907/925 and other products have been released to production.
Moved from there to applications engineer in the high speed DAC product line, supported AD9717, AD9739, AD9789, ADCLK914 and others.
ATMEL STORAGE PRODUCTS, Burnsville, MN July 2001- Jan 2004
Applications Engineer
Provided lab support for a small group designing a DVD +/ R,RW, RAM, CDR/RW capable channel chip intended to work with many different deck designs. Maintained the data sheets.
Designed and constructed the test fixtures, captured waveforms for simulations, architected chip changes for novel deck and format requirements, trained controller IC people in channel operation.
Assisted with UNIX network administration, programmed phone system, learned Cadence Virtuoso XL and did IC layout work such as layout of blocks, and repairing DRC and LVS errors, modifying layout and/or schematic as required. Great teamwork and learning experience
AGERE SYSTEMS (formerly VTC Inc.), Minneapolis, MN 1987- May 2001
Applications Engineer, 1993-2001
Responsible for providing detailed, highly competent technical advice, mentoring, and troubleshooting for internal and external customers.
Applied the industry's first impedance matching to disk drive preamplifier outputs.
Created, designed and developed the "matched writer" concept that led to the current generation of writer circuits.
Identified sources of any customer complaints relating to unwanted oscillations, and developed and implemented appropriate technological solutions.
Internal consultant for all complex signal integrity issues.
An industry resource for better broadband RF design practices.
Test/Product Engineer, 1987-1993
Led product development process from IC design release to production release and ongoing support and maintenance.
Project management responsibilities included scheduling, reporting, test hardware design, software design, and documentation.
First to test high speed comparators for all op-amp specifications.
Designed the company's first (and only) successful fuse trimming methods along with a robust detector circuit for the IC designs.
Created custom hardware and software enhancements to existing ATE systems providing unique reliable solutions for testing high speed mixed digital/linear ICs.
Pioneered AC testing techniques and wafer/package test commonality.
Developed six dollar offset test circuit, replacing $6,000 worth of equipment, 5X better throughput.
PSE, INC., Minneapolis, MN 1977-2001
Designer and Consultant (part time)
Designed the PSE Studio III FM Tuner which employed a unique micro strip front end, dual conversion, PIN diode AGC, and digital detector. Product was marketed and sold for 12 years and is still considered a performance benchmark. Designed a silent cuing system in use on the Minnesota Public Radio network until retired in favor of MP3 adoption. Consultant and sounding board for many preamplifier and power amplifier projects.
