Apple SerDes Circuit Design Engineer United States, Massachusetts, Waltham 100692867
21.11.2024
Description
We 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).
Minimum Qualifications
- BSEE with 3+ years of proven experience.
Preferred Qualifications
- The ideal candidate should have 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
- 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 helpful
- Skills in scripting and automation to improve efficiency are highly desirable
