Abstract

data networks built on Fiber-Optics technology, which sends data digitally, as light through connected fiber strands.A reconfigurable optical add-drop multiplexer (ROADM) is a form of optical add-drop multiplexer that adds the ability to remotely switch traffic from a wavelength division multiplexing (WDM) system at the wavelength layer. In an optical packet network with optical packet switches interconnected with optical fibers running wavelength division multiplexing (WDM), packets are transmitted from source to destination without any optical-electrical-optical (O/E/O) conversion. The optical fiber entering an optical packet switch carries several wavelengths for packet transmission.

Abstract

Crosstalk between interconnects is simulated by SPICE and the results are analyzed. The analysis shows that crosstalk between interconnects can be controlled by repeater insertion and proper sizing of the repeaters. For the best control of crosstalk smallest size repeaters with a number of repeaters is suggested. The dependence of cross-talk on signal transition time and interconnect length are examined and verified with previously reported results. Distributed RLC transmission line model of interconnect is considered.

Abstract

A differential amplifier is an amplifier that amplifies the difference between two voltages and rejects the average or common mode value of the two voltages. The paper presented here is a single input - balanced output cascoded differential amplifier that amplifies a very small signal from the range of nV  up to mV with a gain of 46.02db and operating with a constant gain up to 3MHz bandwidth. This work mainly aims at the amplification of very small input voltage and reduction of overall circuit power dissipation maintaining its linearity. Its application is for lower frequency and very small signal amplification. The total circuit power dissipation is only 32.3uW which is appreciable low. The circuit gain is 200 and it is operated with only 1V. The allowable input peak voltage is from 1nV up to 0.7mV and the output swing without distortion is 280mV peak to peak. For low frequency and low signal amplification this small signal amplifier with low power dissipation can lengthen the lifetime of a chip in IC technology which is powered by battery, if the total power dissipation is low.

Abstract

The importance of food safety is today’s high demand in all over the world. It can cause various harms to human life, if its quality is bad. With increased demand for food quality and health benefits, need for stringent scrutiny on the inspection of agri-food products have become mandatory. The paper presents the development of embedded food sensing system to study the deterioration of food grains under different stress (temperature, humidity, insects etc.) and room environmental conditions. The technique that can be used to sense the food conditions and its quality using ultrasonic transmitter and receiver system with principle of time to digital conversion In this paper, I present a detailed procedure for submitting this paper in the field of food sensing applications. The procedure starts with the important step of selecting the paper topic and continues with finding relevant references, taking notes, doing the actual research, writing the papery. Experimental results were obtained by taking number of samples obtained through different sensing processes.

Abstract

A particle accelerator is a device that uses electromagnetic fields to propel charged particles to high speeds and to contain them in well-defined There are two basic classes of accelerators, known as electrostatic and oscillating field accelerators. Accelerators use static electric fields to accelerate particles. An example of this class is the Cockcroft Walton generator. The high voltage generator of the Cockcroft-Walton accelerator is a well known cascade generator or voltage multiplier circuit. By using only capacitors and diodes, it can step up relatively low voltages to extremely high values, while at the same time being far lighter and cheaper than transformers. The first accelerator of this type was built in 1932 by J.D. Cockcroft and E.T. Walton. They achieved a high voltage of about 700 kV and they studied the first nuclear reaction with an accelerator. They shared the Nobel Prize in physics for 1951.The Cockcroft-Walton generator is discussed in this paper.
