About the role
AMD is searching for an experienced Circuit Design Engineer to define, specify, and implement advanced PLL IPs powering AMD products.
What you'll do
- Design complex building blocks of a PLL, including architecture development and transistor-level circuit design.
- Run pre-tapeout verification flows to confirm design meets performance, power, reliability, and timing requirements.
- Work closely with mask design engineers to deliver physical design and define production/bench-level test plans with post-silicon characterization groups.
- Lead and mentor junior engineers.
What you'll need
- Solid knowledge of mixed-signal circuit design in FinFET technology specifically in PLLs and subblocks including VCO, charge-pump, dividers, state machines, LDO, feedback and compensation techniques, bandgap, TDC, interpolator circuits, and high-speed buffers.
- Solid knowledge of industry standard tools and practices for analog circuit design.
- Working knowledge in physical design, STA, and methodology scripts using Tcl, with knowledge of Perl or Python.
Nice to have
- Master's or Ph.D. in electrical engineering or equivalent.
- Experience in FinFET and Dual Patterning nodes such as 3nm, 2nm, or A14.
- Hands-on design experience in analog and hybrid Phase Locked Loops, ADC, DAC data converters, VCO, LDO, bandgap, charge pump, op-amps, and interpolator circuits.
- Experience with Digital PLL techniques, TDC or DSP and control theory related to digital PLLs, Dual charge-pump PLL designs, Fractional-N PLLs, or spread-spectrum PLLs.
- Proficiency with Cadence custom circuit design tools such as ADE-L and ADE-XL, running Monte-Carlo, noise, aging, EM, IR drop simulations, and stability analysis, with Helic or EMX experience.
- Experience with simulation tools such as Spectre, Hspice, AFS, MATLAB, SystemVerilog, and physical verification tools such as Calibre or ICV for DRC and LVS analysis.
Skills: PLL, FinFET, VCO, charge-pump, Spectre, Cadence
