Flexible and paper electronics have been getting a lot of attention in the last years. Not
only from the scientific community, but also from the end consumer. This ultimately converges
in efforts pushing towards the discovery of new and better materials for the TFT
technology. With this fast development of new devices, compact models for circuit simulation
based on older FETs become obsolete. The availability of fast and accurate models
is an essential part of going from single, proof-of-concept devices, to fully operational
circuits.
In this work, done in the Department of Engineering of the University of Cambridge,
the electrical characterization and parameter extraction of state-of-the-art electrolytegated
transistors (EGT) on paper substrate, fabricated at UNINOVA/I3N, led to the development
of a compact model capable of describing the behaviour of the devices.
A detailed overview of the model is provided throughout this work, from the characterization
of the device, to simple circuit simulations using a dozen of devices. This,
together with the provided Verilog-A code for CAD software implementation, will allow
both new and experienced users in circuit design to simulate simple circuits with these
EGTs or any other TFT device with similar behaviour with simple tweaks on the model
