REFERENCE WORK

Personal Professional Overview:
Edward Olson, Senior GPS/RF Design Engineer

  • Over seventeen years of experience in "whole-product" hardware design and management, from product concepting and specification to design and volume manufacturing
  • Proven senior level project management, design and engineering skills
  • Thorough understanding of GPS tracking, satellite communications, R&D and broad-based knowledge of RF/RFIC/analog/digital technology and industry trends

Focused on GPS integration into products designed for a wide variety of consumer, commercial and military applications. Attention to product concept development, project planning, team leadership, multi-task coordination, critical path, workmanship and budget as they are all vital to a competitive product entry into market.

Global Locate
Silicon Valley-San Jose, California

Technical RF lead for Hammerhead--flagship product & industry's first single-die receiver IC. Responsible for system specifications, collaboration with Infineon design team, design validation. Targeted for mobile handset applications.

Developed leading-edge A-GPS chips for use in mobile phones (e.g. Sharp 904sh), PDAs (e.g. HP iPaq mobile messenger). Achieved receiver sensitivity down to -160dBm, suitable for deep-indoor positioning. Design validation and production test development for LN-22, Global Locate's previous generation RF front-end IC.

RFIC design in 90nm CMOS, constant-gain bias sources, 5th-order Butterworth filter. Simulation using Cadence Virtuoso ADE & Spectre. Taped out successful test chip and RF macro for integration with baseband processor into single-chip receiver.

System design, including frequency plan design, Gain/Noise Figure analysis, Matlab simulation of MASH sigma-delta PLL & Phase-Noise Integration.

Supported customer application of chipsets through design trade-off analysis, interference prevention & mitigation, schematics, PCB layout & performance verification.
