Adiabatic switching techniques based on energy recovery principle are one of the innovative solutions at circuit and logic level to achieve reduction in power. Many researchers had taken adder as a benchmark circuit but advantage of adiabatic can be taken only for a large digital circuit. Barrel Shifter is an important block in the processor design and not much effort has been done to minimize it's power dissipation. A barrel shifter needs nlog2n MUX for n-bit shifting and therefore designing a MUX for low power to use it as a repetitive block in the barrel shifter will considerably reduce the simulation time. This paper compares conventional CMOS based design with adiabatic All the circuits are designed using cell based design approach and 180nm device size in Cadence. The outcome of this research work will provide guidelines for designing barrel shifter using ultra low power MUX . \textcopyright 2008 IEEE.

Deployment of EMC Standards in the design of SMPS

Three-dimensional face-centered-cubic (fcc) photonic crystals (PhCs) are fabricated on quartz substrate using vertical deposition technique, and followed by annealing in a temperature range of 200-700 °C. The monodispersed SiO 2 microspheres with a diameter of 220 nm in colloidal solution are synthesized using tetraethylorthosilicate as a precursor material. The as grown opal structure exhibits a strong photonic band gap (PBG) around 450 nm in the transmission spectrum. We find that the position of PBG peak in the spectrum is relevant to incident angle of light. Moreover, it is very sensitive to annealing temperature. It quickly shifts to short wavelength direction with annealing temperature increasing. The effect results from the decrease in refraction index due to the moisture evaporation in silica microspheres. © 2006.

Fabrication and annealing analysis of three-dimensional photonic crystals

The visual quality of an encoded frame is related to the bits it consumes. To maintain stable quality throughout the video sequence, one needs to consider the distribution of the bit budget for each frame. Within the constraints of bit rate, in order to achieve high visual quality, number of parameters can be considered which include amount of motion present in the video, human visual system, bit allocation, quantisation parameter assignment, motion estimation and mode selection. This paper presents a method, which jointly considers the human visual systems and quality of video to be encoded for rate control. Improvement in performance is obtained as compared to TM5 algorithm used in MPEG2. The proposed technique evaluates the perceptual distortion sensitivity on a macroblock basis, and allocates fewer bits to regions permitting large perceptual distortions for rate reduction. © 2007 IEEE.

Optimum bit allocation using human visual system for video compression

An optical power splitter with one input and three output ports is proposed and demonstrated for near-infrared applications in the wavelength range of 2.3 to 2.5 μm. The device operates on the principle of directional coupling by introducing photonic crystal line-defect waveguides. Its functionality and performance have been numerically investigated and simulated by the finite-difference time-domain method. By cascading two 1 × 3-structure power splitters, a large-scale optical power splitter with one input and five output ports is achieved. The simulated results show that the 1 × 5 large-scale power splitter can also perform 1 × 2, 1 × 3, and 1 × 4 functions. The required optical power from each of the output waveguides can be easily controlled by adjusting the coupling length of interaction for photonic crystal line-defect waveguides. The total length of the 1 × 5 power splitter is 40 μm, which is significantly less than that of the conventional non-photonic-crystal power splitter. This is a promising device for future ultracompact and large-scale nanophotonic integrated circuits. © 2006 Society of Photo-Optical Instrumentation Engineers.

A silicon-based photonic switch is proposed and simulated based on the multimode interference (MMI) principle and the free-carrier plasma dispersion effect in silicon-germanium. The proposed switch, designed for 1.55 μm window operation, is useful for DWDM optical networks. The switch consists of two input single-mode ridge waveguide ports, a MMI section, and three output single-mode ridge waveguide ports. In the MMI section, two index-modulation regions are placed to divert input optical signals from the two input ports to each of the three output ports. Switching characteristics are demonstrated theoretically by a beam propagation method for 1.55 μm operation. The simulated results show that the insertion loss of the switch is less than 1.43 dB, and the crosstalk is between -18 and -32.8 dB.

Design and operation of an encoder involves the optimization of many decisions to achieve the best possible trade-off between rate and distortion under the given constraint on delay and complexity. In this paper, a new ratecontrol algorithm is proposed by optimal bit allocation and macroblock mode selection. It is low-complexity, single-pass algorithm applicable in areas that are sensitive to delay and having very limited resources. Improvement in PSNR is obtained for video sequences with varying contents and bit rate. The algorithm does not violate the buffer constraints. © Indian Institute of Science.

Low-complexity rate-control algorithm for hybrid video coding

A GaN-based optical single-mode rib waveguide with a large cross section is systematically designed and analyzed using the finitedifference vector beam propagation method (FD-VBPM). The method is a combination of numerical aperture and FD-VBPM, which is used to determine the single-mode conditions for a GaN/AlxGa1-xN optical rib waveguide. We analyze the optical propagation properties and loss characteristics of the designed waveguides. The analysis illustrates that optical power increases with an increase of the rib width or a decrease of the slab height. Therefore, our analysis results can be helpful in the process of designing a GaN-based rib waveguide for optical communications. © 2006 Society of Photo-Optical Instrumentation Engineers.

Analysis of GaN-based single-mode rib waveguide with large cross section

The integration of on-board vehicular networks is accelerating today's automobile industry towards the development of next generation hybrid automobiles. This seamless integration of technologies paves the way for the future intelligent transportation system. The existing in-vehicle network techniques provide the features of monitoring various parameters, which are primarily used for evaluating the vehicle's health condition on a real-time basis and to establish suitable control over it as per the observations done. In this paper, a framework for incorporating simple network management protocol (SNMP) based reliable real-time control and performance monitoring system for a hybrid automobile is proposed. Our proposal is based on the usage of SNMP, Control Area Network, and access to the territorial GSM/CDMA networks by using mobile IP. ©2006 IEEE.
