Objective:

Currently working as a research and design engineer for Hewlett-Packard Company.

Education:

B.S. Electrical Engineering & Physics (Double Major) Graduation Date: June 17, 2001
Portland State University, Portland, OR. GPA 3.02/4.0
IEEE Vice-Chair 2001.

Relevant Courses:

Solid State Physics, Quantum Physics, Applied Optics, Electron Optics, Chemistry, Electricity & Magnetism, Thermodynamics, Electric Circuits, Microelectronic Circuit Design, Signals & Systems, Feedback & Control, Digital Circuits, Digital Systems, Microprocessors, Technical Report Writing, Leadership, Digital Signal Processing, Digital IC Design, Lasers System Design, Microwave Circuit Design, and Project Management & Contracts.

Interests & Future Goals:

Currently I am interested in Electro Magnetic Compatibility (EMC), Very Large Scale Integration (VLSI) circuit design, Lasers, and applied optics.

Long term goals include obtaining masters and doctorate degrees in the sciences, as well as inventing and patenting at least one useful technology in my lifetime.

Skills:

Programming Languages - Fortran, C, C+, HTML, 8086 Assembly Language, Very High Description Language (VHDL). Verilog Programing Language will be used during senior design project.

Testing & Verification - Basic skills in testing and trouble shooting of analog and digital circuits include:
  • Taking Measurements with a TDS 420 Oscilloscope using multiple traces and sweeps [4-channels].
  • Use of a function generator setting voltage levels and frequencies to run sweeps as well as analysis of

  •     waveforms such as sine waves, triangle waves, square waves, etc.
  • Verification of signals using tek Spectrum Analyzer and Tek Digital Logic Analyzer.
  • Simulation and verification of analog circuit designs using Analog Design System (ADS) CAD program - Tek
        SPICE and PSPICE programs.
  • Simulation of digital circuit designs using the NOVA functional simulator for programable logic devices and
        Mentor Graphics Software.
  • Simulation of electrostatic and electromagnetic lenses using Simion6 Electron Optics Simulator


  • User of Multiple Operating Systems - Windows Nt, Windows 9X, and Unix.
    Major Projects:

    ECE 321 Design Project - Filter and Oscillator Design.
    Using CAD and SPICE simulation tools and 11th order Low Pass Filter was designed. This filter would most likely be used in audio applications. A Voltage Controlled Oscillator (VCO) implementing a Schmitt Trigger and Howland Current Source was also designed. The target frequency of oscillation was 10.7MHz.

    ECE 322 Design Project - Bipolar Transistor VCO Design.
    Using CAD and Spice simulation tools a Differential Amplifier designed completely at the transistor level was implemented to function as an Operational Amplifier (OPAMP) with high frequency response (10.7MHz). This Differential Amplifier design was then used to implement a VCO using a transistor based Operational Transconductance Amplifier (OTA). The target frequency was 10.7MHz, the intermediate tuning frequency for FM radio tuners. An Emitter-Coupled Multivibrator was also designed and implemented at the transistor level.

    ECE 323 Design Project - Phase Locked Loop (PLL) Design.
    Design and simulation of a Phase Locked Loop at the transistor level. Design of a Gilbert Multiplier functioning as a Phase Detector (PD). Troubleshooting of circuits functioning at high frequencies (10.7MHz). Incorporation of previous two design projects and circuit elements. Major electrical engineering concepts such as communication theory, non-linear circuit analysis and control systems theory were studied and applied.

    ECE 371 Design Project - Microprocessor Programming.
    A program was written in assembly language to program an intel 8086 microprocessor. Using an SDK-86 test board, the assembly code was downloaded to the board and the board functioned as a stopwatch. input/Output functions were utilized in this program for stopwatch display and user start/stop functionality. The working program was verified by the course instructor.

    Senior Design Project - Industry Design.
    Project team consisting of five members working for Hewlett-Packard, Vancouver. One of three members of the Hardware group using Verilog and FPGA's. The other two members worked as the software interface group.
