About the role
Analog Mixed-Signal designer for high-speed SerDes team developing IP for Apple’s SOC. Role involves designing and verifying high-performance AMS blocks for SerDes PHY, leading cross-functional discussions, and delivering IPs that meet quality standards with a focus on power, performance, and area (PPA).
Responsibilities
- Develop high-performance, high-speed AMS circuits used in SerDes PHY (e.g., Rx, CDR, Tx, bias generator, high-speed clock generation, low-jitter distribution, phase interpolator, DLL, VCO, LDO)
- Evaluate circuit topologies to meet product requirements
- Lead discussions with cross-functional teams (architecture, SIPI, packaging, board design, DFT, ESD) to define block-level specifications and behavioral models
- Collaborate with SOC teams to deliver IP views and ensure quality standards
- Drive new implementations/concepts; communicate progress and ideas with peers/management
- Drive lab testing, debugging and data analysis
- Work with analog mixed-signal design teams to create, execute and drive state-of-the-art IPs
- Guide junior engineers and collaborate with large teams to develop TX/RX/PLL components for high-speed IO
- Understand and leverage digitally assisted analog design concepts and LMS-based adaptive loops
Qualifications
- BS and a minimum of 10 years relevant industry experience
- Deep understanding of analog mixed-signal design with experience in high-speed serial links
- Experience designing analog blocks including Bandgap, biasing circuits, LDOs, amplifiers, comparators, switched-cap circuits, ADCs, DACs, Oscillators, Filters
- Understanding of mismatch mitigation, linearity, stability, low-power and low-noise techniques
- Understanding of digitally assisted analog design concepts (e.g., background calibrations, LMS based adaptive loops)
- Proven track record with system/architecture teams to drive block-level and IP requirements for high-speed IO in 100+ Gbps NRZ and PAM applications
- Proven track record of guiding junior engineers on TX/RX/PLL components for high-speed IO
- Experience with high-speed digital circuits (serializer/deserializer, counters, dividers) and digital design concepts
- Experience with TX/RX equalization techniques (CTLE, DFE, de-emphasis) for 100+ Gbps NRZ/PAM
- Experience with EQ adaptation methods to improve PPA
- Solid understanding of CDR architectures
- Experience in Analog Mixed Signal circuit modeling/evaluation (SystemVerilog, Matlab, Python, VerilogAMS)
- Hands-on lab testing, debugging and data analysis
- Hands-on experience with advanced CMOS/FinFET technologies
- Experience with AMS IC development from definition to high-volume production (layout supervision, bench eval, correlation, characterization)
- Timing closure concepts and tools (Nanotime, Primetime)
- IP delivery and quality checks
- Knowledge of high-speed SerDes protocols (PCIe, USB, DP, MPHY) is highly desired
- Scripting and automation skills are highly desirable
