  • Design and develop high-performance and high-speed AMS circuits used in SerDes PHY, including evaluation of different circuit topologies for specific product requirements.
  • Collaborate with multi-functional teams to create and drive block-level specifications, mixed-signal implementations, and behavioral modeling.
  • Work closely with SOC teams to deliver IP views and ensure they meet quality standards.
  • Develop complex IPs on a regular basis and interact with peers/management to communicate progress, discuss new ideas, and drive new implementations/concepts.
Requirements
  • BSEE with 10+ years of proven experience.
  • Deep understanding of AMS design with experience in high-speed serial links.
  • Solid understanding of designing AMS circuit blocks, including Bandgap, biasing circuits, LDO regulators, amplifiers, comparators, switched-cap circuits, ADCs, DACs, Oscillators, Filters.
  • Understanding of analog mixed-signal concepts like mismatch mitigation, linearity, stability, low-power, and low-noise techniques.
  • Deep understanding and experience with digitally assisted analog design concepts (e.g., background calibrations, LMS-based adaptive loops).
  • Proven experience working on system and architecture teams to drive block-level and IP requirements.
  • Proven track record working with large teams and guiding junior engineers.
  • Experience with high-speed digital circuits (e.g., serializer, deserializer, counters, dividers, etc.) with solid understanding of digital design concepts.
  • Experience and proven understanding of Tx/Rx equalization techniques and circuits (e.g., CTLE, DFE, de-emphasis) for 20+ Gbps NRZ and PAM applications.
  • Experience with EQ adaptation methods and circuit interactions to improve PPA.
  • Solid understanding of CDR architectures and implementations.
  • Experience in Analog Mixed-Signal circuit modeling and performance evaluation (e.g., SystemVerilog, Matlab, Python, VerilogAMS).
  • Hands-on experience to drive lab testing, debug, and data analysis.
  • Hands-on experience in advanced CMOS technologies, design with FinFet technology.
  • Hands-on experience with AMS IC development from definition to high-volume production, including layout supervision, bench evaluation, correlation, and characterization.
Preferred Qualifications
  • Concepts of timing closure and related industry tools (e.g., Nanotime, Primetime).
  • Concepts of IP delivery and quality checks.
  • Knowledge of common high-speed SerDes protocols (e.g., PCIe, USB, DP, MPHY) is helpful.
  • Skills in scripting and automation to improve efficiency are highly desirable.
