Responsibilities
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, high-speed analog signal chain, mixed-signal calibration and algorithms) with best in class power, performance, and area (PPA)
Work with cross-functional teams (e.g., architecture, SIPI, packaging, board design, DFT, ESD) to create block-level specifications and execute on transistor-level implementation and behavioral modeling
Drive mask design to implement layout view of designs
Closely work with SOC teams to deliver IP views and make sure they meet the quality standards
Interact with peers/management to communicate progress and discuss new ideas
Qualification
Required
BS and a minimum of 3 years relevant industry experience
