A E R O S P A C E A N A L O G / P O W E R E L E C T R O N I C S E N G I N E E R Good morning!

I am a senior analog design engineer currently seeking a Bay Area opportunity in aerospace analog/power.

My strengths include moving seamlessly between

design, analysis, and project management, with my

forte being power electronics for rad-hard high reliability systems.

I have spent decades working in power electronics

engineering and spent the last ten years contracting with major aerospace firms, including Lockheed Martin, Northrop Grumman, Honeywell, and more.

Please peruse my resume, and feel free to contact me at your convenience. I am currently working from home in Milpitas, CA.

Sincerely,

Don Scoggin

PUBLICATIONS & PROFESSIONAL GROWTH

· Research Paper on “Ferro resonance” voted best paper in Engineering at IBM RTP in 1986. State plane analysis with an IBM PC Junior running compiled BASIC solved a system of linear differential equations used to model non- linear phenomena. The paper was published in the IBM Journal of Research and Development due to its significant advancement of non-linear system modeling.

· Proposed and developed first multiphase buck converter PWM IC, the SC1144AB, in 1998 at Semtech. This novel approach was quickly adopted by Intel and AMD, fueled a tenfold increase in Semtech market value, and became the de facto standard topology for Pentium and Athlon processors.
