Electronic detection of biomolecules has been attracting much interest in the fi elds of clinical diagnosis, pharmacy and biotechnology. In particular, developing highly sensitive, label-free, cost-effective, simple and disposable sensors is strongly required for home medical care. Carbon nanotube fi eld-effect transistors (CNTFETs) with singlewall carbon nanotube (SWNT) conducting channels are...

   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...

   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...

This paper presents arithmetic operations, including addition and multiplication, in the ternary Galois field through carbon nanotube field-effect transistors (CNTFETs). Ternary logics have received considerable attention among all the multiple-valued logics. Multiple-valued logics are an alternative to common-practice binary logic, which mostly has been expanded from ternary (three-valued) log...

We have successfully aligned single-walled carbon nanotubes (SWNTs) in patterns with nanoscale width, micron-scale length and controllable pitch on SiO2/Si substrates using a poly(dimethysiloxane) (PDMS) microchannel mold. The microchanneled mold was patterned with a funnel-shaped channel to minimize nanotube jamming during capillary-driven inflow. Two (i.e. preand post-capillary) gas blows wer...

The p-i-n carbon nanotube (CNT) devices suffer from low ON/OFF current ratio and small saturation current. In this paper by band bending engineering, we improved the device performance of p-i-n CNT field effect transistors (CNTFET). A triple gate all around structure is proposed to manage the carrier transport along the channel. We called this structure multi-segment gate (MSG) CNTFET. Band to ...

Circuit-level implementation of a novel neuron has been discussed in this article. A low-power Activation Function (AF) circuit is introduced in this paper, which is then combined with a highly linear synapse circuit to form the neuron architecture. Designed in Carbon Nanotube Field-Effect Transistor (CNTFET) technology, the proposed structure consumes low power, which makes it suitable for the...
