Process variation is an difficulty in designing reliable CMOS mixed signal systems with high yield. To minimize the variation in voltage gain due to variations in process, supply voltage, and temperature for common trans conductance-based amplifiers, we present a new compensation method based on statistical feedback of process information. We further apply our scheme to two well known amplifier topologies in the sun-micron CMOS process as design examples—an inductive degenerated low-noise amplifier (LNA) and a common source amplifier (CSA). The proposed method improves the variation in S21 of an inductively degenerated cascade LNA from 8.75% to 1.27%, which is a …

Speaker identification is a biometric technique. The objective of automatic speaker recognition is to extract, characterize and recognize the information about speaker identity. Speaker Recognition technology has recently been used in large number of commercial areas successfully such as in voice based biometrics; voice controlled appliances, security control for confidential information, remote access to computers and many more interesting areas. A speaker identification system has two phases which are the training phase and the testing phase. Feature extraction is the first step for each phase in speaker recognition. Many algorithms are suggested by the researchers for feature extraction. In this …

Artificial Bee Colony-Based Design Of Optimal On-Line Self-Tuning Pidcontroller Fed Ac Drives, Innovative Research Publications Irp India, Essamudin A. Ebrahim

Innovative Research Publications IRP India

In this paper, an optimization method based on the foraging behavior of a colony of honey bees in nature was proposed. An optimized model for Proportional Integral Derivative (PID)- speed controller of 3-phase IM drives was introduced to adapt the constant gains of this classical controller. To enhance robustness of this controller, an online algorithm for self-tuning of PID controller-parameters was proposed. Experimental work was introduced using DSP and test results were obtained for several speed trajectories of 2-degree of freedom IM drive and compared with conventional PID controllers.

Li-Fi (Light Fidelity or optical Wi-Fi) is the transmission of data using light waves by varying the light intensity faster than human eye can follow using Visible Light Communication (VLC) technology in free space. This is just like as “Data Through Illumination”. VLC uses rapid pulses of light to transmit information wirelessly. VLC using LEDs is emerging as a key technology for a ubiquitous communication system, because LED has the advantages of fast switching, long life expectancy, being less expensive and being visible light that is safe for the human body. LEDs are different from the other kinds of lamps …

Wireless sensor network consists of a number of energy constrained sensors which are densely deployed in large geographical area. We consider dynamic configuration of wireless sensor networks, where certain functions can be automatically assigned to nodes at any time of network operations, based on the parameters such as remaining energy and topology changes. In order to achieve the topological controlled network reconfiguration the received signal strength indication value along with battery level of nodes were used which indicate any changes in the network layout and remaining energy of the nodes. Based on these two parameters new tasks were then assigned …


Determination Of Some Physical Properties Of Castor (Ricirus Communis) Oil, Innovative Research Publications Irp India, Odesanya Kazeem, Olasheu Taiwo, Adebiyi Kazeem, Durowoju Mondiu Nov 2014

The energy crisis and shortage of fuel emanating from total dependence on mineral oil with resultant socioeconomic problems demand the need to explore the use of renewable energy as alternative. This study evaluates the physical properties of the castor (Ricirus communis) oil. A quantity of 35 kg dried base decorticated seeds of castor was locally obtained, volume of 5 litres of castor oil was extracted from the seeds using existing hydraulic press machine, while its physical properties was determined through laboratory analytical procedure of American Society for Testing and Materials analytical standard 960-52 (ASTM,D960-52). The properties determined were: viscosity, density, …


Power Variation With Electret Surface Potential And Frequency Of Vibration In Vertical Vibration Based Cantilever-Electret Micro-Power Generation, Innovative Research Publications Irp India, Akin-Ponnle A.E, Ponnle A.A, Falaki S.O. Nov 2014

A cantilever-electret based electrostatic micro-power generator for energy harvesting was set up in which Cyclic Transparent Optical Polymer (CYTOP) was used as the electret, and the upper electrode was made in form of an Ashaped cantilever which was fabricated from materials of copper with embedded glass epoxy. The cantilever was vibrated in the vertical direction in close to contact point mode of operation. Experimental result showed that the average output power increases with increasing electret surface potential, and the minimum distance to contact point decreases with increasing electret surface potential. Also, variation of output power with frequency was investigated by …

Increasing need of high security in communication led to the development of several cryptographic algorithms hence sending data securely over a transmission link is critically important in many applications. NIST in the beginning selected Rijndael within October 2000 and formal adoption as being the AES standard started in December 2001. FIPS PUB 197 explains a 128-bit block cipher making Ause of a 128, 192, or 256-bit key. In cryptography, modes of operation enable the repeated and secure use of a block cipher under a single key. This paper presents implementation of multi mode AES algorithm with three modes ECB, CBC …
