Collected and reported historical financial information, managed the cash flow and capital investment, and forecast growth areas and strategic business decisions to differentiate the company from the competition. This business has grown from nothing to over half a million a year in sales and hundreds of thousands dollars of capital investment.

I am a design lead building custom integrated circuits for Apple Inc. My first Thunderbolt product TPS22980 just ramped to production for the mass market as an A0. It has already sold millions.The design cycle of my second product as design lead just completed with the largest wafer chip scale package ever designed for production at Texas Instruments. In.

I was the first employee of the DLP analog MEMs group. As part of a team of three I designed and fabricated an ultra low power 32kHz MEMs based oscillator that consumes less than 2uA total current from a 1.7V supply and yet has jitter performance on par with quartz crystal oscillators. The part features bidirectional communication with a digital state.

I am doing research and development of thermo electric devices using the Peltier effect. Instead of using Bismuth we are using quantum effects in deep submicron CMOS to greatly increase the efficiency of converting a heat transfer into electrical energy.

Due to the difficulty in generating them, terahertz frequencies are the last “undiscovered” portion of the frequency spectrum. Situated between infrared and microwaves, many elements and compounds have rotational and vibration modes in the frequency band.Inexpensive sources and detectors of terahertz frequencies can open the doors to reliable and.

• Modeled, designed, simulated and measured highly efficient and very low cost digitally controlled oscillators that are compliant across four major GSM bands in both 90nm and 65nm CMOS digital processes.
• Invented a circuit technique to improve close in phase noise performance.
• Developed methods and invented a circuit to maintain reliable 3.3V internal signal swing in 90nm, 65nm and 45nm oscillators. In each successive process node I improved tuning range and/or phase noise.
• Debugged an oscillator reliability problem tracked back to a fab issue.
• Last oscillator design focused on 3G using a 45nm process. Tuning range was 36% and 3.6GHz phase noise was -155dBc/Hz at 20MHz offset.
• Designed and simulated the capacitor and inductor components for each process node along with the general oscillator layout.

• Directed design team in developing the transmit function for TI’s 65nm 2.5G single-chip cell phone. Met overall system specifications and insured the oscillator transistors were reliable under very large signal swings..
• Led on-time development and delivery of a transmit system for $900M 90nm 2G single-chip GSM cellular phone for Nokia. Coordinated resources from four countries to test and develop software and delivered customer.
• I set the required scope and experiment list of 10 test chip projects.
• Led a virtual team to deliver the design, layout, and measurement of each test chip in 65nm and 45nm digital CMOS processes.
• Each project was delivered on-time without errors over a four year period with a typical budget of $500,000 per project.
