Day By Day

Use of analog circuit elements in active networks have become very common and the demand for their miniaturization is increasing day by day. Though several methods are available for the miniaturization of these elements through large scale integration on single chips, the performance is not very satisfactory in low-frequency applications, due to the presence of parasitic capacitance that is comparable to the capacitance of active elements. As a result, the desired response gets deviated and also noise is involved. In this paper, an attempt has been made to devise methods for the elimination or reduction of the influence of these parasitic capacitances on filter circuits.

This Paper Describes our Challenge of Automatic Analog Circuit Design by Focusingon a Comparator Circuit which is One of the Important Analog Building Blocks. the Geneticalgorithm Chooses the Optimal Circuit Topology and HSPICE Optimizing Function Obtains Theiroptimal Parameter Values Automatically. Automatic Design for Analog Circuit has Not Beenrealized yet, even though Automatic Design is being Used in Digital Circuit Design; the Reasonbehind this is that the Number of Parameters to Be Considered in an Analog Circuit Designis much Larger than Digital Circuit Design. Nowadays it is Extremely Difficult to Design Icsmanually due to their Large Scale Integration and Hence their Automatic Design is Demanded. Wepresent our Automatic Circuit Design Owchart Programmed with Java Language which Realizes1-Click Automatic Synthesis of the Comparator, and Shows that our Method can Obtain a Betterperformance Comparator Compared to an Initially-Set Comparator.

And Function

Plants seem to be rather defenceless, they are unable to do motion, have no nervous system or immune system unlike animals. Besides this, plants do have hormones, though these substances are produced not in glands. In view of their complexity they lagged behind animals, however, plant organisms show large scale integration in their structure and function. In higher plants, such as in animals, the intercellular communication is fulfilled through chemical messengers. These specific compounds in plants are called phytohormones, or in a wide sense, bioregulators. Even a small quantity of these endogenous organic compounds are able to regulate the operation, growth and development of higher plants, and keep the connection between cells, tissues and synergy beween organs. Since they do not have nervous and immume systems, phytohormones play essential role in plants’ life. Orv. Hetil., 2014, 155(26), 1011–1018.

Behavior Models

Background: The symbolic nodal analysis acts as a pivotal part of the very large scale integration (VLSI) design. Methods: In this work, based on the terminal relations for the pathological elements and the voltage differencing inverting buffered amplifier (VDIBA), twelve alternative pathological models for the VDIBA are presented. Moreover, the proposed models are applied to the VDIBA-based second-order filter and oscillator so as to simplify the circuit analysis. Results: The result shows that the behavioral models for the VDIBA are systematic, effective and powerful in the symbolic nodal circuit analysis.</P>
