Presenter Bio

Jasmin Aghassi-Hagmann is a full Professor of Electrical Engineering at the Karlsruhe Institute of Technology with a Research Unit on Electronic Devices and Systems at the Institute of Nanotechnology, KIT. She has received her Master in Physics (Diploma) from the RWTH Aachen and her PhD from Karlsruhe University (KIT) in theoretical physics. For six years she worked as a research engineer at Infineon Technologies and Intel on advanced CMOS technology nodes. Her expertise is in printed electronics, semiconductors and devices, in particular in design and simulation, electrical characterization and inkjet printing of electronic devices.

Her current research (Aghassi lab) focuses on printed inorganic semiconductors such as metal oxides, printed electronic devices, in particular electrolyte-gated transistors, memristors as well as hybrid circuits for sensing, bioelectronics and security applications.

Abstract: Sensor design and circuit implementation using a flexible hybrid organic process design kit
Printed and flexible electronics enable interesting novel applications in the fields of sensors and bioelectronics. To design complex circuitry and hybrid integrated systems, the sensor and the near sensor computing part is fabricated in printed electronics, which are complemented by silicon electronics to form an integrated hybrid system. I will show how we have developed a dedicated flexible hybrid organic process 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. As an example for the capability of our FH_OPDK I will show a flexible pressure sensor integrated with an organic active matrix backplane addressed by binary decoders and analog multiplexer based on organic field effect transistors and metal resistors.   [1] G.
