General Summary:

About the role

Qualcomm’s Mixed-Signal IP high-speed clocking and Phased Locked Loop (PLL) design team is seeking Analog / Mixed-Signal design engineers to join our team in Cork, Ireland. The successful candidate will work on analog and mixed-signal integrated circuits for high-speed clocking IP for SoC and PHY level integration into Qualcomm's Mobile, Auto, IoT & Compute SoC products. The primary focus of the work is on low-power and low-voltage mixed-signal design with emphasis on advanced nanometer FinFET & Gate-All-Around (GAA) technology nodes.

The successful candidate will both design key circuit blocks and work closely with layout engineers to ensure the layout is fully optimized and complies with best analog layout practices. You will be directly involved in delivering next-generation PLL designs for Qualcomm SoCs and will be part of a large analog mixed-signal design team involved in architecture analysis and IP delivery in leading-edge process technology nodes at 3nm and beyond.

The role requires industry experience in transistor-level circuit implementations or highly relevant academic experience in a Masters’ or PhD program focused on full custom analog circuit design using nanometer CMOS technologies. In addition to Analog and Mixed-Signal circuit design expertise, good understanding of device physics, analog circuit custom layout, power distribution networks (PDN), mixed-signal design flow, SoC top-level integration and IC Design Tools are desired.

Responsibilities:

  • Architecture, design, and development of analog / mixed signal hard macros for the high-speed clocking IP Design team

  • Perform custom circuit design in the latest processes technologies and beyond to support the delivery of clocking (PLL/DLL/FLL) IP

  • Participate in internal customer requirements discussions.

  • Create design specifications.

  • Create behavioural models in Verilog.

  • Set-up, run and analyse circuit simulations.

  • Perform quality assurance procedures on developed hard macros.

  • Deliver hard macros and support customer integration and testing.

  • Perform silicon characterization analysis and prepare silicon verification reports.

Skills and Experience we would love to see:

  • Master’s or Ph.D. degree in Science, Engineering, or related field.

  • A minimum of 5-years of transistor level analog mixed-signal design experience, preferably in frequency synthesis design, high-speed wireline SerDes, DDR or other high speed applications

  • Experience in SPICE simulators and schematic capture tools

  • Experience in designing op-amps, bandgaps, differential amplifiers, VCO, PLL, DLL, FLL

  • Understanding of signal integrity in high-speed wireline design is preferred

  • Scripting to automate circuit design and verification work

  • Full-custom analog layout techniques and the ability to take a design and do all the layout extract verification and sign-off

  • Excellent communication skills and ability to contribute strongly within a high-performance team
