Electronic Devices and Systems

Welcome to the research unit of Prof. Aghassi-Hagmann in which we explore electronic devices and systems in future technologies with a special focus on printed electronics. We are an interdisciplanary group of electrical engineers, physicists, material scientists and computer scientists located at KIT campus north working on printed materials, novel nanomaterials, micro/nano-structured devices, additive manufacturing techniques and systems in the field of future electronic technologies. We strive for gaining understanding from materials to device level and to develop solutions for electronic, bioelectronic and energy applications.

If you are interested in our research or seek job oppertunities do not hesitate to contact us.

Tutorial on Using our Flexible Hybrid Organic Printed Electronics PDK (FH_OPDK)

Within the 2Horisons BMBF-Project on printed sensor nodes the consortium (Cadence, KIT, BASF, IL and University of Heidelberg) is offering a tutorial on using Flexible Hybrid Organic Printed Electronics PDK (FH_OPDK) to design circuits for Integrated Sensor Platforms. We have developed a dedicated design kit, suitable for running in commercial CAD Tools (Cadence Virtuoso) which supports a full front to back design flow. The design flow includes schematic entry, initial simulation, and layout generation for prototyping. Additional we have developed dedicated transistor models, capacitance models as well as parasitic extraction to allow for high precision modelling.

In the video on the right you can see the creation of a demonstrator using the FH_OPDK. During the tutorial you will be able to try out creating designs using this PDK and Cadence tools installed in a cloud environment. The PDK can be downloaded unter our section Software.
