• Develop understanding of the digital and photonics subsystem and associated requirements on the AMS sub system.
• Utilize knowledge general concepts of high-performance analog design and compare various topologies that best fit the AMS architecture to support AI application requirements.
• Enhance system performance using digitally assisted analog techniques and appropriate partitioning of analog and digital circuits.
• Drive transistor-level feasibility study for various AMS circuits.
• Define design specifications and verification plans.
• Define production and bench-level test plans.

QUALIFICATIONS

• Requires Master's Degree or PhD in related areas of expertise.
• 10+ years of experience AMS Design.
• Experience with architecture, design, and production expertise in the following areas:
• • High-speed data converter architectures and circuits
  • Ultra-low-power analog circuits.
  • Digitally assisted analog circuits.
• You should be highly skilled in the following areas:
• • MATLAB/Simulink/Verilog A modeling.
  • Data converter architectures and design trade-offs
  • Low-power and high-precision analog techniques.
  • Architect circuit solutions that achieve challenging noise, linearity, power consumption, and silicon area requirements.
  • AMS design flows and chip assembly techniques.
  • Working with design, layout, and production test engineers.
  • Excellent communication skills are necessary to work with multiple domain experts, such as digital/VLSI, AI/ML, Photonics, and packaging.
