PLL Design Engineer

Job Title: PLL Design Engineer
Location: Irvine/San Jose, CA (Partial remote)
Duration: Full-Time

What You Will Do:
Understand trade-offs between different PLL topologies (e.g., integer-N, fractional-N, all-digital/ADPLL) to meet specifications for power, area, jitter, and frequency range
Architect, design and simulate analog/mixed-signal PLL building blocks (VCOs, charge pumps, dividers, PFDs, Loop Filters) at transistor level using tools like Cadence Virtuoso and Spectre
Address challenges in advanced node technologies, such as self-heating, electromigration, voltage-controlled oscillator (VCO) linearization and device-level noise optimization
Supervise and verify layouts produced by layout engineers to ensure floorplanning, matching, and parasitic minimization using advanced node technologies
Be responsible for PLL bring up in the lab, conducting performance characterization using state-of-the-art lab equipment
Conduct comprehensive system-level simulations and validation for PLL integration into advanced transceiver technologies
What You Will Bring:
Master’s degree and/or PhD in Electrical Engineering or related fields with 5+ years of relevant experience in PLL design, and production level tape-out experience.
Must have extensive experience with advanced node technologies (16nm/12nm, 7nm, 5nm, 3nm, 2nm processes)
Deep understanding of phase noise analysis, VCO design, LDOs and supporting circuitry associated with PLLs
Proficient in cadence virtuoso, electromagnetic simulator (e.g., EMX/HFSS), and MATLAB for system-level modelling
Strong communication and documentation skills
