The noise characteristics of randomly networked single-walled carbon nanotubes grown directly by plasma enhanced chemical vapor deposition (PECVD) are studied with field effect transistors (FETs). Due to the geometrical complexity of nanotube networks in the channel area and the large number of tube-tube/tube-metal junctions, the inverse frequency, 1/f, dependence of the noise shows a similar l...

Motivations of CMOS technology scaling are higher speed of operation, benefit of integration density and lower power dissipation. CMOS technology has crossed many hurdles over the past four decades. The aggressive technology scaling is causing device parameter variations, which is more severe than earlier. This paper carries out variability analysis of various popular exclusive-OR circuits at t...

In this article a low power and low latency 4-2 compressor has been presented. By using modified truth table and Pass Transistor Logic (PTL) a novel structure has been proposed which outperforms previous designs from the frequency of operation view point. The proposed design method has reduced the total transistor count considerably which will lead to reduced power consumption and smaller activ...

Nowadays, there is a high demand for sensitive and selective real-time analytical methods suitable wide range of applications, from personalized telemedicine, drug discovery, food safety, quality control, to defense, security, as well environmental monitoring. Biosensors are devices able detect bio-chemical analytes (e.g., neurotransmitters, cancer biomarkers, bio-molecules, ions), through the ...

Electronic detection of biomolecules, although still in its early stages, is gradually emerging as an effective alternative to optical detection methods. We describe field effect transistor devices with carbon nanotube conducting channels that have been developed and used for biosensing and biodetection. Both transistors with single carbon nanotube conducting channels and devices with nanotube ...

We probed the charge transfer interaction between the amine-containing molecules hydrazine, polyaniline, and aminobutyl phosphonic acid and carbon nanotube field effect transistors (CNTFETs). We successfully converted p-type CNTFETs to n-type and drastically improved the device performance in both the ON- and OFF-transistor states, utilizing hydrazine as dopant. We effectively switched the tran...
