Energy Harvesting From Water Droplet Motion Confined On A Hydrophobic-Hydrophilic Stripped Surface

CYTOP is a hydrophobic material which has high charge trapping potential because of high breakdown voltage in the range 132 V/μm, The developed device works on the variable capacitor model, and converts mechanical motion of droplet into electrical energy. Design and developed of the reported device is simple and relatively faster than conventional energy harvesters and MEMS devices. Peak voltage of 1.5 V and 3.1 V were observed for pure and ionic water (5 wt% NaCl) for 50 μL, of droplet respectively when it rolls over the hydrophilic channel.

The two biquads (a VMbased biquad and a CM-based biquad) are combined efficiently to form a hybrid biquad that can be digitally controlled to convert into either of the two with similar responses. The workability of the new circuits has been well established by SPICE simulation results of their CMOS-implementable versions.

Radix-2 booth’s algorithm is explained, it is then identified that the main bottleneck in terms of speed of the multiplier is the addition of partial products. Radix-4 Booth’s algorithm is presented as an alternate solution, which can help reduce the number of partial products by a factor of 2.The booth’s multiplier is then coded in Verilog HDL, and area and timing analysis is performed on it. Radix-4 Booth’s multiplier is then changed the way it does the addition of partial products by utilizing a configuration register for range detection to reduce the number of partial product additions. Results of timing and area are then shown. The results table contain device utilization and timing results of 2 multipliers i.e. Radix-4 booth’s multiplier) and radix-4 modified booth’s multiplier with configuration register. Index Terms Booth’s multiplier, Radix-4, Xilinx, Multiplier, Ve...

The filter is realized using Simulink. The filter is optimized for the size of adders and subtractors in terms of the word length by reducing the word length of consecutive adders to save area and computational complexity. The designed filter is converted to a Verilog RTL using the HDL coder in MATLAB. This filter is implemented in Xilinx and simulated in ISIM simulator for white noise, impulse and step response for 1000 samples. An optimized Verilog RTL implementation of the same filter is also presented. This optimized code is less complex and understandable and has the same functionality with lesser resource utilization. Index Terms – Decimation filters, CIC filters, Verilog RTL, Filter design, Filter implementation. ________________________________________________________________________________________________________

Sigma Delta ADC consists major portions of the modern VLSI designs, thus efforts are being made to design low power ,small area sigma delta ADCs using different topologies and methodologies. This paper discusses various existing Sigma Delta modulator designs and topologies, consisting of different number stages and optimizations from one another. This paper focuses on the study of these designs and their comparison on the basis of parameters like power dissipation, structure order, bandwidth, OSR, FOM etc. All the designs studies are application and technology specific but the output bit patterns are similar for similar inputs with variations in rate of output. The simulation environment for the structures was chosen to be PSPICE A

For wider acceptance of such nano-composites, the deposition and integration process flow optimization in terms of patternability and piezoelectricity is required. In this paper, we report an optimum process flow for ZnO/SU-8 based nano-composite thin films for energy harvesting applications. By varying various patterning parameters, the optimally deposited 15% weight ratio based ZnO/SU-8 nano-composite thin film shows the optimum results with good piezoelectric voltage and transmittance characteristics for reliable photo-lithography. The trade-off between the piezo-response and photopatternability is analyzed using both experiments and finite element simulations. Furthermore, two types of energy harvesting devices are fabricated using the same nano-composite as an active layer which ...
