Amorphous InGaZnO (a-IGZO) is a candidate material for thin-film transistors (TFTs) owing to its large electron mobility. The development of high functionality circuits requires accurate and efficient circuit simulation that, in turn, is based on compact physical a-IGZO TFTs models. Here we propose a compact physical-based and analytical model of the drain current of a-IGZO TFTs. The model accounts...
This paper presents the first printed organic 13-MHz RFID on flexible substrate. The proposed solution includes a planar near field antenna bonded to an RFID tag, which is printed on flexible foil using an organic complementary TFT technology. Thanks to an active envelope detector, ASK modulation with modulation depth as low as 20% can be adopted to increase the available input power for the rectifier...
In the last several years, organic electronics have gained increasing consideration as a cost-effective alternative to silicon, especially in RFID applications. An inductive-coupled organic RFID operating at 13.56MHz was demonstrated on foil using p-type organic technologies [1]. A complementary organic technology was used for a 13.56MHz transponder in [2]. Recently, a complementary hybrid organic/metal-oxide...
Organic transistors (OTFTs) can be printed on thin plastic substrates to obtain mechanically flexible large-area electronics with high throughput. Examples of applications include sensor-augmented RFIDs fabricated on the packaging of retail items and smart surfaces integrating sensors or actuators. Printed OTFTs have been used to design circuits [1–4], however, these implementations have been mainly...
