Mixed-Signal Circuit for Consumer Device

I need a complete mixed-signal circuit designed for a new piece of consumer-grade electronics I’m developing. The job covers the full path from concept to production-ready files: translating high-level functional requirements into a detailed schematic, validating the design through simulation, and handing over neat, fabrication-ready PCB layouts with an up-to-date bill of materials. The circuit blends low-noise analog front-end blocks with a modest-speed digital section driven by a microcontroller, so proven experience balancing analog performance against digital switching noise is essential. I expect all design work to be done in a mainstream tool such as Altium Designer, KiCad, or Cadence OrCAD/Allegro—whichever you are fastest with—while simulations can run in LTspice, PSpice, or an equivalent platform. Deliverables • Annotated schematic (PDF + source) • PCB layout files and Gerbers/ODB++ • BOM with manufacturer part numbers and current availability • Simulation results that verify critical analog and digital performance metrics • Short design report explaining key choices and how EMI, power integrity, and thermal limits were addressed Acceptance Criteria The design must meet 3.3 V single-rail operation, achieve <2 mVpp analog noise on the input stage, and pass a basic DFT review for automated assembly (minimum 0.25 mm clearances, proper test pads, etc.). Files should open error-free in the stated CAD tool. If you have prior work on similar consumer electronics or mixed-signal boards, point me to it so I can gauge fit quickly. I’m ready to start as soon as I find the right partner.
