“…Mutual collaboration between research teams at Brno University of Technology (The Microelectronics Department at The Faculty of Electrical Engineering and Communication represented by Mr. Roman Prokop and The Faculty of Information Technology) has enabled the creation of polymorphic gate with two inputs, whose function is controlled by supply voltage [11]. The fundamental goal of this joint effort was to come up with a gate design which is compatible with wide-spread CMOS based circuits (one of the essential requirements that should facilitate its use together with conventional CMOS gates on a single chip).…”

The paper presents a new design approach to digital circuits that provides for an increased chip operation reliability from temperature point of view. The key aspect behind the proposed method of approach is to avoid chip overheating due to special design and subsequent integration of dedicated circuit controller. Such element is blended seamlessly with the surrounding circuitry and posses the ability to reconfigure itself when the temperature of the chip goes beyond defined temperature boundary. After the end of reconfiguration phase, the controller ensures only indispensable function. By this arrangement, the power and heat dissipation of the circuit is reduced until the chip temperature falls again under certain level. When the chip is cooled down appropriately, the controller returns back to normal operating mode automatically. The proposed approach utilises principles of polymorphic digital circuits which embrace smart and fast reconfiguration, compact and costeffective design with embedded sensors, where the aim is to ensure overall system stability and in the same time increase its dependability.

In this paper, a new reconfigurable polymorphic chip (REPOMO32) is introduced. This chip has been developed in order to investigate the electrical properties of polymorphic circuits and demonstrate the applications of polymorphic electronics. REPOMO32 contains an array of 32 configurable logic elements; each of them can perform the AND, OR, XOR and polymorphic NAND/NOR function which is controlled by the level of the power supply voltage. REPOMO32 parameters are reported together with the analysis of polymorphic circuits implemented and evolved in REPOMO32. Potential applications of the chip are also discussed.

Complementary circuits based on organic electrochemical transistors (OECTs) are attractive for the development of inexpensive and disposable point-ofcare bioelectronic devices. Ambipolar OECTs, which employ a single channel material, could decrease the fabrication complexity and manufacturing costs of such circuits. An ideal channel material for ambipolar OECTs should be electrochemically stable in aqueous environments, afford facile ion insertion for both cations and anions, and also facilitate high and balanced electron and hole transport. In this study, triethylene glycol functionalized diketopyrrolopyrrole (DPP)-based polymer is proposed for the development of ambipolar OECTs. It is shown that DPP-based OECTs have a high and comparable figure of merit for both n-and p-type operations. Logic NOT, NAND, and NOR operations with corresponding complementary circuits constructed from identical DPP-based OECT devices are demonstrated. This study is an important step toward the development of sophisticated complementary metal-oxidesemiconductor-like logic circuits using single-component OECTs.
