The Carinthia Institute for Microelectronics (CIME) is a competence center for research and development of integrated electronic systems. CIME is strongly associated to the department of Integrated Systems and Circuits Design (ISCD) with a close network to other departments within the faculty of Engineering & IT at Carinthia University of Applied Sciences.
Integrated Circuits (ICs) became a key technology for modern electronic systems embedded in almost any application of our daily life ranging from data processing, telecommunications, medical electronics, automotive and power electronics to any kind of miniaturized sensing networks. The monolithic integration of billions of transistors on a single silicon chip with an area of a few cm2 enables nowadays reliable and cost-efficient electronic platforms with enormous computing and signal processing power for future electronics.
The research on integrated electronic circuits and systems is a well-established discipline at our institute, started in the early days of Carinthia University of Applied Sciences (CUAS). Since more than 20 years, our researchers are working on cooperative research funded by industry and national / European projects in the field of wireless and wireline communications as well as integrated sensor frontends.
CIME is intended to be a competent research partner, with strong alignment to industry needs and the clear focus on research excellence with international visibility. This is also based on the research of Josef Ressel Center “Interact” which was operated at CUAS until 2019. The required specific education and know-how exchange in the field of microelectronics is supported by the Master degree program “Integrated Systems and Circuits Design – ISCD” and PhD positions in cooperation with other Universities.
During past 10 years the microelectronics research group has successfully initiated and operated funded research projects with an overall budget volume for CUAS of approximately 5.5 M€
CIME can offer research expertise and support in the following fields of microelectronics
- RF and high-speed integrated circuits for wireless and wireline communication
- Analog and mixed-signal integrated circuits for sensor front-ends
- Embedded digital signal processing and application specific processors
- Modelling and design automation/generation of integrated electronic systems (eg. SystemC – AMS, System Verilog, Matlab, Python) and EM simulations with finite-element solvers
- System-on-chip design as well as System-in-Package integration
- Modern CAD environment with tape-out experience in most state-of-the-art IC technologies (CMOS 350nm, 180nm, 65nm and 28nm)
- Lab characterization of integrated circuits including PCB-design, chip assembly (wire-bonding) and IC needle-probing
CIME - Research
CIME is organized in three departments “RESPECT”, “RFFE-Lab” and “SIMS” focusing on different research topics. The “Research Lab for Radio Frequency Frontends” (RFFE-Lab) is a cooperative research lab, jointly operated with Silicon Austria Labs and co-located at CUAS. In May 2023 the official opening of the „JRZ for System-on-Chip Automation SODA“ will take place.“
Modelling and Design of Integrated Systems and Circuits
The research lab for “Modelling and Design of Integrated Systems and Circuits” at the Carinthia University of Applied Sciences is working on IC Design of IP building blocks, modelling of electronic systems and SoC design automation.
Radio Frequency Front-Ends
The “Radio Frequency Front-Ends Lab” is merging research on RFIC design, RFMW design and RF components. Miniaturization demands and increasing functionality of modern integrated communication devices are facing numbers of challenges.
Sensor Integrations in Mechatronics Systems
This research group will be an intensified, multi-disciplinary research collaboration with RESPECT (RF wireless) and CISMAT (Carinthia Institute of Smart Materials ) for Mechatronic sensor integration in the development of integrated wireless sensors and smart manufacturing/smart living.
Josef Ressel Centre for System-on-Chip Design Automation
This centre aims to research revolutionary new methods for the development of „system-on-chips“ in modern semiconductor technologies and to advance the automation of the development process of integrated circuits. – OPENING EVENT 23rd May 2023
Modern solutions of wireless RF systems require multi-standard multi-band functionality for future software defined radio and agile radio products (operated at Carinthia University of Applied Sciences (CUAS) from 2014 until 2019).
