  • MEMS Based Ultrasonic Imaging and Therapy
    Micrograph of a surface micromachined capacitive ultrasonic transducer fabricated in SUNUM.

    MEMS based ultrasonic transducers offer great opportunities in the realization of integrated ultrasonic systems for diagnosis and therapy. Owing to the fact that close integration is a must for signal fidelity, improved performance calls for the design of application specific integrated circuits (ASICs). This makes the co-design of MEMS transducers and the associated electronics a very exciting research field.

    • Analytical and Numerical Modeling of MEMS devices.
    • Design and Manufacturing of MEMS based Ultrasonic Transducers
    • Analog/Digital and High-voltage IC Design for Transducer Interfaces

Radio Frequency and Millimeter-wave Antenna and Circuits Design

Group's research areas cover various topics of microwave engineering especially designing antennas and RF active circuitry. Researches include both theoretical and practical phases. To conduct practical experiment, there are well-equipped and high-tech laboratories, like SUNUM, at Sabanci University. Having millimeter-wave (W-band) setup makes it possible to do antenna and circuit measurement. Automotive radar at 77GHz is group's ongoing major project. This high tech radar system can be used at cars for collision avoidance, park aiding and navigation. This project includes designing antenna, LNAs, phase shifter and etc at W-band frequency range.

General research interests include:

  • Antenna and Propagation Modeling
  • RF integrated circuits design
  • Millimeter wave antennas and circuits measurement setup
  • Indoor positioning GPS system
  • Dielectric measurement

SiGe BiCMOS Technologies with “More-than- Moore” Modules for mm-wave and THz Applications

In last decade, SiGe BiCMOS technologies open a new cost-efficient market at mm-wave frequencies. Starting with the commercial use of automotive radars at 77 GHz, the market now has a strong interest on radar, sensor and imaging products at mm-wave and sub-THz frequencies. The latest developments on SiGe HBTs with fmax of beyond 700 GHz boosts the research and development effort on circuit and system area to take share from the new market. In parallel to the developments on SiGe HBT performance, “More-than-Moore” path, which covers all the additional functionalities to the standard CMOS process (i.e. MEMS devices, microfluidics, etc…), allows to realize multi-functional circuits and systems.

Our research activities are running under the IHP – Sabanci University joint lab (http://www.ihp-microelectronics.com/en/joint-labs/sabanci-university-istanbul/overview.html) and covers the following research themes:

  • SiGe BiCMOS based mm-wave and THz semiconductor technologies
  • RF Micro-Electro-Mechanical-Systems (RF-MEMS)
  • mm-wave and THz silicon based device and circuit design
  • Heterogeneous Integration and System-in-Package (SiP) technologies for high frequency electronics
  • THz sensor and microfluidics applications for bio-electronic systems

The research objective of Sabancı University MicroElectronics Research group (SUMER) is to use new technologies, techniques and architectures to develop novel integrated devices, sensors/detectors, circuits and systems and explore the continuous advances of micro/nano-electronics to promote their usage and exploitation in real-life application fields.

While achieving our research objectives, we educate our BSc, MSc and PhD students to become top-level academician, scientist or engineer, who can contribute to science and/or industry by successfully dealing with the challenges and applying the high-level fundamental research and knowledge to advance science and technology.

The research group mainly focuses on 5 major research areas;

  • High frequency integrated circuit design up to 240 GHz (RFIC, mm-wave IC, 5G, Terahertz Imaging, Radiometry)
  • Mixed signal integrated circuit design (ReadOut Integrated Circuit (ROIC) design for infrared imaging systems, ADC, DAC, etc.)
  • Energy harvesting,
  • Biosensor and biosensor interface design,
  • MicroElectroMechanical System (MEMS) design for different applications.

Many ongoing and completed projects, that are supported by leading companies of the industry, The Scientific and Technological Research Council of Turkey (TÜBİTAK), Turkish Ministry of Science, Industry and Technology, European Union, are conducted by the members of the research group.
