About the role

SoC Power Integrity Engineer responsible for development, implementation, and verification of power integrity solutions for compute and connectivity SoCs used in Apple devices. Lead end-to-end PI studies, define PDN architecture, model and verify PDN across die/package/module/PCB/PMU, and collaborate with cross-functional teams to ensure impedance, droop, and noise specifications are met.

Responsibilities

  • Definition of the PDN architecture and design solution space for systems across a wide range of power and noise specifications.
  • Power delivery modeling, simulation, and characterization for die, package, module, board, and Voltage Regulator (VR)
  • Definition of the PDN architecture and design solution space for the target system
  • Broad responsibility on all SoC PI related topics, including on-die inrush, off-die droop budget, PDN signoffs, digital to analog/RF noise coupling analysis, voltage guard band, active droop mitigation etc.
  • Lead end-to-end PI studies including modeling of die/PKG/Module/PCB/PMU to meet stringent impedance, voltage droop, and noise spec
  • Provide implementation guidelines and actionable feedback to silicon, package, system design and other cross-functional teams.
  • Drive feasibility study for silicon floorplan, advanced droop mitigation schemes, voltage regulator modeling and tuning, system mockup design
  • Perform model to hardware correlation on component/module- and product/system-level
  • BS and 10 +years of relevant industry experience
  • MS or PhD preferred with background in Power/Signal Integrity, Power Electronics, Electromagnetics, Microwave, and/or Analog/RF Circuit Design.

Qualifications

  • BS and 10+ years of relevant industry experience
  • M.S. or Ph.D. with academic background in Power/Signal Integrity, Power Electronics, Electromagnetics, Microwave, and/or Analog/RF Circuit Design.
  • Understanding of power supply architecture covering multi-stage voltage regulator technologies, PCB and package design trends and trade-offs, and chip supply design including low-power and high-power design methodologies.
  • Experience in PI/SI methodology development, PDN modeling from system to die, and lab correlation/validation in time-/frequency-domain.
  • Proficiency in Python coding, AI/ML assisted automation experience.
  • Experience in design and analysis of product power supply solution.
  • Deep understanding of Voltage Regulator design principles and electrical performance in the system environment.
  • Good knowledge in 3D/2D EM simulation tools, electromagnetic and transmission line theory.
  • Preferably working knowledge on analog/RF/wireless noise coupling and sensitivity
  • Familiar with lab equipment including but not limited to VNA, real-time scope, spectrum analyzer.
  • Ability to work and communicate efficiently in cross-functional teams.
