Institute for Integrated Circuits

The Institute for Integrated Circuits provides expertise for all main steps in the design and realization of integrated circuits, embedded systems, as well as cyber-physical systems. This includes modeling of corresponding HW/SW systems in early stages of the design flow and their realization through all major abstraction levels such as the Electronic System Level (ESL), the Register Transfer Level (RTL), the gate level, and the technology mapping down to the physical/analog level. A particular focus represents the design of corresponding applications in the domain of analog and mixed-signal circuits (Internet of Things) and medical technology.

The Institute for Integrated Circuits is composed of the following departments:

Energy-Efficient Analog Circuits and Systems

The Department for Energy-Efficient Analog Circuits and Systems covers the design of analog and mixed-signal circuits and systems, with emphasis on low-power circuit techniques, radio-frequency integrated circuits, power-management and energy harvesting. Using our strong background in circuit and systems design for cellular communications we are exploring novel power amplifier technologies, 5G cellular communication, low-power wireless sensor networks and new approaches in energy harvesting and power management.We are also active in the area of electro-static discharge protection of circuits and systems which special consideration of electromagnetic interference. For students, we offer lectures for graduate and undergraduate students and supervise Bachelor as well as Master theses. In addition, PhD theses are offered for further studies.

Integrated Circuit and System Design

The Department for Integrated Circuit and System Design covers the development of design methods for various application areas. A particular focus of our work is on the design, verification, and test of circuits and systems for conventional as well as alternative and post-CMOS computing technologies. Besides that, we have proven to successfully apply the methods developed by us in complementary research areas. For students, we supervise Bachelor as well as Master theses. We believe in research-oriented learning.
