Reliability study of organic complementary logic inverters using constant voltage stress
نویسندگان
چکیده
We performed constant voltage stresses with different bias conditions on all-organic complementary inverters. We found a 20% maximum variation of DC inverter parameters after a 10-s stress. However, the largest stress-induced degradation was found in the delay times, which increased by a factor as high as 7. This is mainly due to the threshold voltage variation of the p-type thin-film-transistor and the mobility reduction of the n-type thin-film transistors, which both decrease the saturation drain current. 2015 Elsevier Ltd.

Tuning the Threshold Voltage in Organic Thin-Film Transistors by Local Channel Doping Using Photoreactive Interfacial Layers
In recent years, organic thin-fi lm transistors (OTFTs) have attracted a great deal of attention due to their potential applications in low cost sensors, [ 1 ] memory cards, [ 2 ] and integrated circuits. [ 3 ] Great efforts are under way to design OTFTs with high performance, high stability, high reproducibility, and low cost. [ 4 ] Two of the most crucial device parameters are the charge carr...
متن کاملCascading wafer-scale integrated graphene complementary inverters under ambient conditions.
The fundamental building blocks of digital electronics are logic gates which must be capable of cascading such that more complex logic functions can be realized. Here we demonstrate integrated graphene complementary inverters which operate with the same input and output voltage logic levels, thus allowing cascading. We obtain signal matching under ambient conditions with inverters fabricated fr...

In this paper we present robust and high performance static ultra low-voltage CMOS binary logic. The delay of the ultra low-voltage logic presented are less than 10% of the delay of standard CMOS inverters. The logic gates presented are designed using semi floating-gate transistors and a current boost technique. The boolean gates resemble domino CMOS. The performance and robustness of different...

Brushless DC motor (BLDCM) has been broadly used in drive systems and servo control because of its fast response, high power density, high efficiency, low inertia, high reliability and maintenance free. It is however driven by a hard-switching PWM inverter, which has low switching frequency, high switching loss, high electro-magnetic interference (EMI), high acoustic noise and low efficiency, e...
