Description
As an RFIC-PLL Designer, you will provide analog and digital PLL solutions for wireless SoC and drive them to mass production for Apple. Responsibilities include: - Lead design of radio transceiver chains including analog PLLs - VCOs, digital PLLs - DCOs, LOGen, and chain of blocks in RX, and TX for wireless connectivity products.- Drive radio KPI (power, area, performance) to meet product requirements - Work with multi-functional teams, including platform architecture, wireless design, RF HW, and SW, to define radio features enabling wireless innovation. - Work closely with RF Systems on block-level and high-level specifications of the PLL-LOGen, TX, and RX line-ups and the accurate distribution of spec margins in the chain.- Design of RF and Analog loopbacks for calibration and compensation.- Work through Co-Existence scenarios and design to meet the CoEx requirements.- Lead all aspects of the floorplan layout and verification of the design to ensure a successful tape-out.- Provide design versus silicon measurements correlation and compliance with volume production specifications.
Minimum Qualifications
- BS and 10 + years of relevant industry experience.
- Solid experience with RF/analog and mixed-signal design experience in groundbreaking RF CMOS design.
- Experienced in the design and development of fractional N Synthesizers, Digital PLLs, Analog PLLs, and LO-Gen for high-performance applications and also low power applications.
- Hands-on experience in designing TDC, GRO, Digital Filters, Sigma Delta Modulators, Pre-scalers, and MMD, DCOs, PFD-CP, and VCOs. Modeling, analysis, and design of SD noise cancellation and spur cancellation techniques.
- Experienced in Cadence Virtuoso, Spectre RF, Matlab, EM simulation (EMX, HFSS), and similar tools.
- Familiarity with mixed-signal mode verification methodology (SystemVerilog, AMS, Nanotime).
- Extensive experience in fractional N synthesizer and LOGen silicon characterization and debugging.
Preferred Qualifications
- Direct experience in designing and bringing wireless transceivers into mass production in deep sub-micron RFCMOS technology.
- Deep understanding of analog, mixed-signal, and RF circuit design. This includes LNAs, PAs, mixers, baseband filters, VGAs, and calibration methods associated with high-performance wireless systems.
- Familiarity with various RF transceiver architectures and their trade-offs, system specifications, and ability to work with system architects to translate system requirements into circuit requirements at the IC level.
- Proven capability working with digital design group for an optimum partition between digital and analog domain, and timing requirements.
- MSEE and/or PhD with extensive experience.
