This article presents a dual-mode (voltage-mode and current-mode) universal biquadratic filter performing completely standard functions: lowpass, highpass, bandpass, band-reject, and allpass functions, based on plus-type dual-output second-generation, current controlled, current conveyor (DO-CCCII+). The features of the circuit are that the bandwidth and(More)
Carbon nanotubes, especially the ones with diameters of the order of a few nanometers exhibit correlated electron transport and are best described using the Tomanaga Luttinger liquid model. Recently the TL model was used to create a convenient transmission line like phenomenological model for carbon nanotubes. In this paper, we have attempted to quantify(More)
We have developed a computer simulator for the asynchronous sequential circuits (ASCs) constructed by using the random access memories (RAMs). This is a generic simulator with respect to the manufacturing technology of the RAM because all the time delays are variables and can be changed by the user. In addition, there is no restriction on the RAM size. The(More)
Metallic carbon nanotubes are being considered as a candidate for to potentially replace Copper as an interconnect material in future generation integrated circuits. In this paper we examine electronic transport behavior in metallic carbon nanotubes using a self consistent non equilibrium Green's function (NEGF) methodolgy including effects of electron(More)
In this paper, a 16 channel 25 Gbps DWDM optical network is simulated and analyzed for 120 km using dispersion compensating fiber. The system is operated on -10dBm of Input Power. NRZ-DPSK modulation format is used for transmission under symmetrical compensation schemes. Group velocity and third order dispersion are compensated to improve the Q-factor.(More)
