Role summary
Apple is seeking an Analog/Mixed-Signal Circuit Design Engineer to join their AMS team. This role involves designing and delivering hard IPs for Apple products, focusing on SERDES, high-speed data converters, PLLs, memory interface circuits, and clocking circuits. The engineer will work with multi-functional teams to architect and design circuits, drive mask design, coordinate with IP consumers, define test plans, and conduct design reviews. The position requires a BS in Electrical Engineering and 20+ years of experience, with preferred knowledge in advanced CMOS technologies, lab testing, and behavioral modeling.
Description
We have ownership lead development of analog & mixed-signal circuits including SERDES, high-speed data converters, PLLs and other analog mixed-signal circuits. You will be working with multi-functional teams to architect and design innovative analog/mixed-signal circuits. You will also drive mask design to implement layout view of designs. You will coordinate with IP consumers, help define production/bench-level test plans, and conduct design reviews of blocks with peers/management to show design meets spec targets and requirements.
Minimum Qualifications
Bachelors of Science in Electrical Engineering and 20+ years experience.
Preferred Qualifications
In-depth knowledge of analog mixed-signal concepts like mismatch mitigation, linearity, stability, low-power and low-noise techniques Experience with high-speed digital circuits (e.g., serializer, de-serializer, counters, dividers, etc.) Design experience in advanced CMOS technologies such as 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 lab testing of mixed-signal circuits and experience in using spectrum analyzers, oscilloscopes, signal generators, etc. to validate analog designs Able to build VerilogA/AMS behavioral models, analyze and lead characterization data from lab and volume testing Ability to drive results, drive what matters and manage complexity Excellent written and verbal communication skills and ability to solve challenging cross-functional problems in a team environment Solid understanding and expertise in crafting analog/mixed-signal circuit blocks including ADCs, DACs, SERDES, PLLs, DLLs, filters, bandgap, biasing circuits, LDO regulators, amplifiers, comparators, switched-cap circuits and oscillators
