About the Job

Requirements

  • A Master's degree with at least 2 years of experience or a PhD with 0 years of experience in a related field.
  • Extensive hands-on experience designing PLLs in deep-submicron CMOS processes from 5nm to 28nm, including at least one of integer-N, fractional-N, digital PLL, or sub-sampling PLL topologies.
  • Deep understanding of PLL system theory, including phase noise, jitter, loop dynamics, reference spurs, and fractional spurs.
  • Proficiency with IC design CAD tools such as Spectre, SpectreRF, and an AMS simulator.
  • Strong MATLAB/Simulink skills for behavioral modeling and system-level analysis.
  • Familiarity with Verilog/SystemVerilog for mixed-signal simulation.
  • Solid understanding of layout-sensitive design and ability to guide critical PLL layout, including LC tanks, charge pumps, and reference paths.
  • Lab characterization experience, including phase noise measurement, jitter analysis, and spectrum analysis equipment.
  • Experience with RTL design in Verilog/SystemVerilog to implement PLL-related digital calibration circuits, including frequency calibration, phase calibration, and background self-calibration logic.

Responsibilities

  • Design PLLs and clock generation circuits, including integer-N, fractional-N, digital PLLs, and clock multipliers/dividers, for RF and SerDes applications.
  • Design critical PLL building blocks, including VCO/DCO, charge pumps, loop filters, phase/frequency detectors, dividers, and phase interpolators.
  • Perform PLL system-level modeling, noise analysis, and jitter budgeting using MATLAB/Simulink.
  • Drive design verification, including transistor-level simulation, Monte Carlo analysis, and silicon correlation.
  • Collaborate with digital, layout, and systems teams to deliver PLL IPs that meet performance, power, and area targets.
  • Support bring-up, characterization, and debugging of silicon prototypes in the lab.
