Memristor memories provide non-volatile and high density solutions that can overcome some of the challenges faced by CMOS technology. Memristor memories use the memristor as a resistor and depict a logic 1 by a high resistance state and a logic 0 by a low resistance state. Typically, the memristor's resistance range is divided in half, and a state falling in the lower half depicts a logic 0 and the...
The continuous demand for high storage capacities in modern electronic systems has made it more than ever important to find memory technologies beyond CMOS that are able to cope with the challenges at the nanoscale while catering to the requirements of high performance and robust operation. Memristors are excellent candidates for post CMOS memories, owing to their nanoscale nature and their programmability...
Due to their orthogonality and nearly constant pulse widths, Modified Hermite Pulses (MHPs) have shown a great potential to enhance the data rate of UWB communications by creating M-ary or multiple access parallel systems. However, the potential high power dissipation required by the pulse set generation and the frequency shifting has limited their utilization in practice. In this paper, we propose...
In this paper, we analyze the compact models for carbon nanotube field-effect transistors (CNTFET) and observe that the logic-gates implemented using CNTFET with unoptimized device parameter have asymmetric voltage transfer characteristic. We propose the design of a balanced inverter circuit implemented using CNTFET devices. The proposed inverter circuit is functional over a wide range of supply voltage,...
The theory of compressive sensing has recently been utilized to develop sub-Nyquist communication receivers that can reconstruct the input signal using sub-Nyquist sampling rates. Such samples are acquired randomly by projecting the input signal on random signals. Practically, these random signals can be generated by digital pseudo random signal generators, and the properties of these signals highly...
Biomedical implants have been developed in the recent years with a focus for continuous and real-time monitoring of physiological parameters. Battery-less operation of the implanted unit requires energy harvesting from an inductive link or from the neighboring environment. For efficient conversion of harvested energy to a usable DC level, a rectifier block is employed. However conventional CMOS full...
We study the scattering of light by nanoegg dimers using a computational scheme that allows for the efficient simulation nanoegg dimers. Nanoegg dimers exhibit high field enhancements and field focusing owing to the broken symmetry in the geometry of nanoeggs, in addition to higher tunability than symmetric nanoparticle dimers. We utilize the quasistatic approximation combined with translation relations...
In this paper we study the high order resonance modes in a nanoegg and how the core displacement affects the properties of such modes. We use the quasistatic approximation, which is valid because nanoeggs typically resonate at wavelengths much larger than their size.
Nanoshells promise to be valuable in a wide range of applications ranging from chemical sensing to cancer treatment. Different applications require different performance from the nanoshell and pose different constraints on them, and thus the nanoshell sensor has to be designed according to the given application. In this regard, the resonance wavelength and the Q factor are the most important properties...
Modeling nanostructures using circuit components have been useful in the enhancement of the design process of nanostructures. Given the use of nanoparticles in a wide range of applications, it becomes important to establish efficient models that can capture the properties of nanoparticles efficiently and accurately. Asymmetrical nanoparticles are more complex to model due to the symmetry breaking...
