Introduction

Welcome to the website of the Department of Microelectronics at TU Delft.

With a staff of about 30 fte faculty and over 180 fte scientific staff, the Department of Microelectronics combines the expertise of 7 research groups in Electrical Engineering. The complete field of electronics is covered, including signal processing, radar, and telecommunication.

Microelectronics is fundamentally a multi-disciplinary field of research, exploring the physics, materials and chemistry required to make devices work. It is also multidisciplinary with regard to its wide variety of applications, as it plays a crucial role in all fields of innovation, ranging from advanced health care to telecommunications and smart grids. The ever-increasing demand for processing power, sensing capabilities and miniaturisation makes microelectronics a highly innovative research field.

The Department is involved in several MSc tracks: MSc Telecommunication and Sensing Systems, MSc Signals and Systems, MSc Microelectronics.

Research at the Department of Microelectronics spans all major aspects of electronic engineering including the design and development of silicon-based devices, analogue and digital circuits for smart sensors, biomedical implants and wireless communication systems, signal-processing algorithms for communication and biomedical signals, as well as microwave and terahertz systems for remote sensing and radio astronomy.

ME’s research is a major contributor to a number of EEMCS themes:

  • Health and Wellbeing - from materials to systems, with specific expertise in:
    • diagnostic technology : visualization and tumor detection, high-Tesla MRI, ultrasound arrays and other sensors
    • monitoring with low power wireless technology and implantable stimulators, such as cochlear implants and neural stimulators for treatment of tinnitus;
  • XG - Next Generation Sensing and communication - from devices to systems:
    • energy-efficient electronics
    • scaling of frequencies from GHz to THz - with the promise of Gb/s wireless networks
    • advanced signal processing , such as 'cognitive radio ', use of large antenna arrays
    • communication for localization and control
    • underwater RF and acoustic communication
  • Safety and Security - from material to systems:
    • microwave vision
    • distributed sensor systems for environment monitoring
    • large sensor arrays and applications in security and radio astronomy
    • resource management in distributed sensing systems

The Department provides expertise for each of these research areas, throughout the whole system chain, from the technology layer to the sub -system and component layer and to the system layer, with a direct link to the challenges facing today's society.

Capacitively-Coupled Bridge Readout Circuits

This Ph.D. dissertation describes the design and realization of energy efficient readout integrated circuits (ROICs), that have an input referred noise density < 5 nV/√Hz and a linearity of < 30 ppm, as required by Wheatstone bridge sensors used in precision mechatronic systems. Novel techniques were developed, at both the system-level and circuit-level, to improve the ROIC’s energy-efficiency, while preserving its stability and precision. Two prototypes are presented, each with best-in-class energy efficiency, to demonstrate the effectiveness of the proposed techniques.

3D Elements for Phased-Array Systems: Analysis and Design.

Phased arrays for radar and communication systems require supporting frequency and angular selectivity functions to reduce interference and enable more flexible operation. Frequency selective surfaces with large rejection bands and their integration with phased arrays are investigated. Moreover, array of tilted dipole elements are proposed to achieve radiation with asymmetric field of view.
