Leader in Integrated ICT Hardware & Systems

Senior Mixed Signal PMIC Silicon Designer for Ultra Low Power Systems

SOD-4 Senior Mixed Signal PMIC Silicon Designer for Ultra Low Power Systems

Contract: Full-time/ Fixed Term

Established in 2004, the Tyndall National Institute is one of Europe’s leading centres in ICT research and development. It hosts over 460 researchers, engineers and support staff. It has a network of over 200 industry partners and customers worldwide. Tyndall performs breakthrough research in photonics, electronics, micro/nano-technology and smart systems to deliver innovative solutions in the communications, energy, medtech, biopharma, agricultural and the environmental sectors.

Tyndall is host to both the SFI (Science Foundation Ireland) Irish Photonics Integration Centre (IPIC) and the Enterprise Ireland/IDA Microelectronics Circuits Centre Ireland (MCCI). MCCI’s mission is to carry out industry-led world-class Analog, Mixed-Signal and RF integrated circuit research and to deliver trained people and IP to industry.  MCCI is already collaborating with 35 companies and many of the staff eventually transfer into the thriving microelectronics industry in Ireland. 

Tyndall Micro-Nano-Systems Circuits Group, in conjunction with MCCI, wishes to offer an eighteen-month fixed-term research and development role in the area of mixed signal control system design and implementation on CMOS, for integration with our ultra-low-power energy harvesting PMIC platform.

The role primarily involves modelling, design and simulation of mixed-signal control systems to maximise energy transduction from a range of µW-level ambient energy harvester types including PV, TEG, and Piezo Vibrational, into both energy storage devices and into regulated system voltages. The control systems will be developed for Tyndall’s ultra-low power buck-boost power conversion IC platform. The IC will be the central controller for technology show-case designs such as highly integrated energy-source-in-package, eSiP. The designs are to be a basis for next generation energy-harvesting or ultra-long life battery powered smart-sensor nodes, as might be appropriate for IoT or Body-Wearable application.

Multi-disciplinary and multi-domain models for the various harvester types will be created in Matlab/Simulink. Linear Time Invariant (LTI) controllers will be developed to implement voltage, current, power and energy control loops for the above harvester types around averaged models for the switch mode converter feeding into both super-capacitor and battery storage devices. The control systems developed will be predominantly implemented as asynchronous Verilog RTL and will be synthesised as digital state-machine blocks on 180 nm CMOS IC.  

The role might suit a control designer who enjoys multi-disciplinary theoretical analysis and will contribute to the group’s research publications.

Key Responsibilities

  • Modelling, design and simulation of mixed-signal control systems to maximise energy transduction from a range of µW-level ambient energy harvester types including PV, TEG, and Piezo Vibrational, into both energy storage devices (supercapacitors and rechargeable cells) and into regulated system voltages. Energy conversation will be through ultra-low power multi-mode buck-boost.
  • Design of digital controllers (Z transform and discrete time domains) to implement voltage, current, power and energy control loops for the above harvester types around averaged models for the switch mode converter.
  • Implement the designed controller blocks in Verilog RTL (substantially asynchronous for ultra-low power).
  • Synthesise designed controllers as digital circuit blocks (to transistor level) on CMOS (Timing, Place and Route).
  • Design of electronic hardware prototypes and test schematics to prove devised controller blocks with FPGA based hardware.  
  • Assist with integrated power system prototype characterisation and the dissemination of results, as directed by and with the support of a Senior Researcher or Principal Investigator through to tier one conference technical paper publication.
  • Engage in appropriate training as required.
  • Participate in Education and Public Engagement activities, as required.
  • Ensure all activities are compliant with the Tyndall Quality Management system.
  • Ensure all activities are compliant with the required Health and Safety standards.
  • Carry out any additional duties as may reasonably be required within the general scope and level of the post.

Essential Criteria

  • Minimum of a Bachelor’s Degree (honours) in Electronics Engineering or related discipline with 6 years’ experience in Analog, Mixed-Signal or RF integrated circuit design

- OR -

  • Master’s Degree in Electronics Engineering with 4 years’ experience in Analog, Mixed-Signal, PMIC or RF integrated circuit design
  • Evidence of successful execution of Analog, Digital, Mixed-Signal, PMIC or RF circuits at block level through to tapeout.
  • Experience of digital block design for implementation on CMOS.
  • Ability to work independently on the design of challenging mixed signal circuit blocks.
  • Good planning, organisational and communication skills.
  • Strong evidence of being a self-starter and highly motivated.
  • Experience of contributing well in a team-oriented, collaborative environment.

Desirable Criteria

  • PhD in Electronic and Electrical Engineering.
  • Experience of mixed signal system level modelling in Matlab-Simulink or System Verilog.
  • Experience of implementation of real time control algorithms in FPGA.
  • Good understanding of switch mode power circuit operation.
  • Good understanding of magnetic component operation.
  • Good understanding of state-space averaging.
  • A publication or patenting track record.
