Key Qualifications

  • The ideal candidate will have 15+ years of RF/analog and mixed-signal design experience, with 7+ years management experience in cutting-edge RF CMOS design.
  • Direct experience designing and bringing into high volume production ZIF RF transceivers in deep sub-micron RFCMOS technology. This includes design of on-chip LNAs and PAs, PLL/VCO/LO blocks, up-conversion/down-conversion mixers, baseband filters, data converters and calibration methods associated with such high performance wireless systems and ZIF designs. Experience should also include understanding of DFT and DFM techniques for high volume production environment.
  • Extensive knowledge of all or many of the following fields:
  • Deep understanding in system specification and able to work with system architects to translate system requirement into circuit requirement at IC level; Requires strong understanding of impact of modulation type to radio architecture and requirements.
  • Familiar with various RF transceiver architectures and their trade-offs; Demonstrate the capability to work with digital design group for an optimum partition between digital and analog domain;
  • Deep understanding of fundamentals of RF CMOS implementation, and basic building blocks, including LNAs, mixers, VCOs and DCOs, LO and PAs;
  • Deep understanding of RF device modeling, including but not limited to device noise parameters, inductor modeling. Insights into packaging effects, supply isolation, high frequency ESD structures, and circuit layout techniques for optimum RF performance;
  • Requires strong knowledge of desense and able to work closely with board RF/HW/Antenna teams to optimize board/module layouts for desense mitigation. Also, has experience with desense mitigation with integrated PMUs/DSPs (i.e. substrate isolation, return loops, package isolation, frequency planning, etc).
  • Familiar with mix signal mode verification methodology (SystemVerilog, AMS, Nanotime)
  • Familiar with EM tools (EMX, HFSS)
  • Extensive experience in Si characterization and debug
  • Ability to drive strong production test/QA methodologies.
  • Extensive experience in IP sourcing and management
