An Improved VCO Design with Negative Feedback to  Reduce Jitter at High Frequencies

This paper presents an improved design of voltage controlled oscillator (VCO) utilizing the three differential cell CMOS inverters for forming the ring oscillator. The differential cell reduces the power supply fluctuations impact on the oscillator jitter while the negative feedback from frequency to voltage converter reduces the jitter at high frequencies. Finally the proposed model is designed using CMOS 0.18um foundry technology and simulated using P-Spice software. The result shows that the proposed design improves the jitter attenuation at different offset frequencies up to 40dB

Response of UV-B Radiation on Germination Percentage,  Growth Pattern and Chlorophyll Content at see

Capsicum annum L. (Syn: Capsicum frutescens L., family: Solanaceae) is an herbaceous spice plant cultivated in tropical and subtropical conditions in different countries of the world. In India it is commonly known as “Lal Mirch”. The present study deals with response of UV-B radiation on different growth parameters of capsicum crop. Plants were grown in the field and exposed to supplemental UV-B radiation (280-320nm) for 1 hr and 3hr regularly supplied by the sunlamp, 300 watt from sowing till seedling stage. The total UV-B irradiation received by the plants from the lamp was 24.23 Jm -2 s -1 . The seed germination percentage was significantly decreased by 1 hr and 3 hr UV-B irradiation. The exposure of 1 hr UV-B irradiation showed promotory response on chlorophyll content and biomass of plumule and cotyledons while exposure of 3 hr of UV-B irradiation showed inhibitory effect on growth and chlorophyll content of seedlings. Current findings suggest ways to increase crop

Design of 32Bit Carry-lookahead Adder using  Constant Delay Logic

This paper presents an enhanced 32-bit carry lookahead(CLA) adder implementing using the constant delay (CD) logic, targeting at full-custom high-speed applications. The CD characteristic of this logic style regardless of the logic type makes it suitable in implementing complicated logic expressions such as addition. CD logic exhibits a unique characteristic where the output is pre-evaluated before the inputs from the preceding stage is ready. This feature offers performance advantage over static and dynamic domino logic styles in a single-cycle multistage circuit block. Several design considerations including timing window width adjustment and clock distribution are discussed. Using 65-nm general-purpose CMOS technology, the proposed logic demonstrates an average speed up of 94% and 56% over static and dynamic domino logic, respectively, in five different logic gates. Simulation results of 8-bit ripple carry adders show that CD logic is 39% and 23% faster than

This study had investigated on the possibility of blood leaf( Iresine herbstii) as a soil pH indicator. An aqueous solution was prepared and settled to remove impurities. The pH is 4.6. The solution was tested in a 0-14 pH solutions to check on the color changes in the scale. The soil pH was tested using pH paper and pH meter. The soil pH was also tested using the blood leaf extract and the tests showed the same result. In conclusion, the aqueous extract of blood leaf can be used as soil pH indicator. This can benefit gardeners and flower growers because they can use it as fresh extract or can be kept even for many weeks in closed container.

 Genetic Algorithm for Wireless Sensor Network With Localization Based Techniques

In wireless sensor network nodes position estimation in space is known as localization. Node localization in wireless sensor network is important for many applications and to find the position with Received Signal Strength Indicator requires a number of anchor nodes. However the estimation of distance from signal strength decay in not very accurate especially in time varying environmental conditions and the estimation of exact direction required highly directive antenna but, may still affected by multipath fading. A Genetic Algorithm for wireless sensor network localization is proposed in this paper to solve the issue that the positioning accuracy is low with minimum anchor nodes. Hence in this paper we are presenting a Genetic algorithm for optimization approach which tries to find the optimal location by satisfying both the criteria with minimal error. The simulation results also shows effectively outperform both the techniques.
