All-Digital Circuits for Measurement of Spatial Variation in Digital Circuits

Static Simulation of CNTFET-based Digital Circuits

   In this paper we implement a simple DC model for CNTFETs already proposed by us in order to carry out static analysis of basic digital circuits. To verify the validity of the obtained results, they are compared with those of Wong model, resulting in good agreement, but obtaining a lighter ensuring compile and shorter execution time, which are the main character...

Dynamic Simulation of CNTFET-Based Digital Circuits

   In this paper we propose a simulation study to carry out dynamic analysis of CNTFET-based digital circuit, introducing in the semi-empirical compact model for CNTFETs, already proposed by us, both the quantum capacitance effects and the sub-threshold currents. To verify the validity of the obtained results, a comparison with Wong model was carried out. Our mode...

Digital Circuits

In this paper we present a method for obtaining a functional partitioning of the logic of a computer. It is shown that given a basic function to be performed, such as addition, the computer logic can be partitioned into four disjoint sets, namely the active information logic X, the semiactive flip-flops 9', the activated control logic %, and the dormant logic 9. Techniques involved in implement...

Flexible and transparent all-graphene circuits for quaternary digital modulations.

In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air or cables. Here we report a flexible all-graphene modulator circuit with the capability of encoding a carrier signal with quaternary digital information. By exploiting the ambipolarity and the nonl...
