My Services

I provide electronic and FPGA design services to support your outsourcing needs. My electronic design services include circuit design, circuit simulation and PCB layout. Certified by Xilinx, I offer FPGA design services including VHDL programming, simulation and verification for all Xilinx FPGAs.

My Portfolio

I have designed electronic circuits for many applications and markets including consumer products, hospital systems, emergency communications systems, high-performance digital signal processing, optical communications and laser control. Please take a look at my work for past clients and employers.

About Me

My name is Jeff Johnson, I am an electronic design expert with more than a decade of professional experience in electronic product development. In 2013, I created a consulting company to help meet the industry’s need for a design service that is flexible and competitively priced without compromising on quality.

My services have already helped…

Here’s what my customers have to say…

We had Opsero design and build a complex controller board for us using the Zynq 70z20 dual ARM core with FPGA and multiple special analog features DAC’s, ADC’s programmable I/O supplies etc. Jeff had good knowledge and understood well what we were trying to accomplish. We used his experience with the chip to help us determine best paths for the design. His communication with my team was top notch and he stayed on top of the job during a long trip he had long planned, allowing us to keep on schedule. We would highly recommend him and will use him on future projects.

Jeff’s expertise proved to be invaluable for our product development. His passion for electronics resulted in higher quality standards in combination with cost reductions. A remarkable achievement.

Patrick Kooijman

I have been very pleased with Jeff’s knowledge and accomplishments on the Virtex5 FPGA. He understands the ISE, XPS and SDK platforms as well as the ML506 eval board. His response to the project design and changes has been excellent. He has been very reasonable and fair with his time estimates. I have no hesitation in highly recommending him to anyone who needs FPGA help.
