Description
You will work on the development of high-performance and high-speed AMS circuits used in SerDes PHY, including evaluation of different circuit topologies for specific product requirements (e.g., Rx, CDR, Tx, bias generator, high-speed clock generation and low-jitter distribution, phase interpolator, DLL, VCO, LDO) with best in class power, performance, and area (PPA).You will be leading discussions with cross-functional teams (e.g., architecture, SIPI, packaging, board design, DFT, ESD) to create and drive block-level specifications, mixed-signal implementations and behavioral modeling. You will closely work with SOC teams to deliver IP views and make sure they meet the quality standards. While developing these complex IPs, on regular basis you will interact with your peers/management to communicate progress, discuss new ideas and drive new implementations/concepts making it a rewarding and growth-oriented work environment.
Minimum Qualifications
- BSEE with 10+ years of proven experience.

- The ideal candidate should have deep understanding of analog mixed-signal design with experience in high-speed serial links.
- Solid understanding and experience of designing analog mixed signal circuit blocks including Bandgap, biasing circuits, LDO regulators, amplifiers, comparators, switched-cap circuits, ADCs, DACs, Oscillators, Filters
- Solid understanding of analog mixed-signal concepts like mismatch mitigation, linearity, stability, low-power and low-noise techniques
- Solid understanding and experience with digitally assisted analog design concepts (e.g. background calibrations, LMS based adaptive loops)
- Proven track record of working with system and architecture teams to drive block-level and IP requirements
- Proven track record of 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 solid understanding of Tx/Rx equalization techniques and circuits (e.g. CTLE, DFE, de-emphasis) for 64-100+ 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
- Experience in the following areas is a plus
- 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 highly desired
- Skills in scripting and automation to enhance efficiency are highly desirable
