Confidential 10/14-present

Consulting Engineer

Designing low noise 16 bit Raman spectrometer for use in natural gas exploration

Utilized Spartan3AN non-volatile FPGA for image sensor control and image processing.

Design included automatic baseline control of image, low noise sigma delta image capture of image, various filtering techniques for displaying the image and multiple TEC controllers.

Zeiss Meditech, Dublin, CA 2/13 – 10/14

Consulting Engineer

Image processing in hardware to prevent the laser in a laser driven eye examination system from burning the eye of the patient.

The design was FPGA based (non-volatile Spartan 3an) and included acquiring the reflected image from a laser x,y galvo deflection system.

System included serval FPGAs and high speed static rams and the FPGA code was written in VHDL.

Pinebrook, Santa Clara, CA 7/12 – 2/13

Consulting Engineer

Camera design using 3 color 1kx1k Foveon CMOS sensor for use in a direct laser exposure PCB manufacturing system. Camera was used to monitor l the laser exposure of the PCB.

The camera design was FPGA based (Spartan 6) and the FPGA code was written in verilog

Fairchild Camera, Milpitas, CA 10/09 – 7/12

Senior Engineer

System design and hardware design of a low noise (16 bit) CMOS camera for scientific applications using a camera link interface.

The design is FPGA based (Spartan 6) and includes bad pixel correction, offset and gain corrections/pixel, hi and lo gain blending, binning, 16 possible ROI and an embedded microblaze processor for handling auto focus, light levels and general control functions.

The design also included a high speed internal block transfer bus for image processing, a camera link interface and a PWM controller for a peltier TEC that was maintained at a camera temperature of +/- .05C.

Designed color 16k pixel aerial surveillance camera using 2 concatenated 6 inch line scan sensors. Altera FPGAs (StraTix and Cyclone) used to control line scan sensors and to seamlessly abut the pixels of the two sensors.

Camera interfaced to compute through proprietary PCB.

Gatan, Pleasanton, CA 12/07 – 03/09

Senior Engineer

System design and hardware design of a low noise (16 bit) CCD camera for electron microscopes.

Performed both analog and digital design.

The design was FPGA based (virtex 5) and included horizontal overscanning, vertical overscanning, and digital CDS for increasing the number of effective bits.

The design also included a DSO (digitals sampling oscilloscope) in the FPGA to allow tuning of the CCD drive signals while the camera was cooled and in a vacuum.

All CCD timing was programmable by use of memory mapped execution tables that resided in the FPGA.

The FPGA controlled all CCD clocking signals to a Resolution of 75 pico seconds.

All of the advanced features of the Vertex5 were used in this design.

A customized Serdes interface transferred the image from the camera

Lightfleet, Camas, WA 8/06-10/07

Consulting Engineer

System design and hardware design of a super-computer using a novel all to all interconnection scheme.

FPGA designs for direct high speed switching (10 Gbs) between any source computer blade and possibly multiple destination computer blades.

Implemented Lattice FPGAs in both Verilog and VHDL. Lattice was used because it offers a large number of high speed serial ports.

Grass Valley, Beaverton, OR 10/05-7/06

Consulting engineer

Hardware design of a video compression/decompression server for driving projectors for the movie industry.

FPGA design done in Verilog. Schematic entered in Cadence.
