Hi, my name is Joel Feigenbaum. I have 13 years of experience in primarily low to medium frequency analog circuit design with some digital design. I have worked with companies such as Hughes Aircraft and Lear Astronics. I've designed power amplifiers, signal conditioning, synchronous modulation, RFI/EMI problem debugging, etc. I'm experienced in doing worst-case analysis and circuit simulation using SPICE. Give me a description and I'll design it and build it for you in a reasonable amount of time and at a competitive cost.
