The performance of multiplication in terms of speed and power is crucial for most of the Digital Signal Processing (DSP) applications. Many researchers have come up with various multipliers such as array, Booth, carry save, Wallace tree and modified Booth multipliers. However, for the present day applications Vedic multipliers based on Vedic Mathematics are presently under focus due to their high...
The guard zone G (of width r) of a simple polygon P is a closed region consisting of a set of straight line segments and circular arcs (of radius r) bounding the said polygon such that there exists no pair of points p (on the boundary of P) and q (on the boundary of G) having their Euclidean distance d(p, q) less than the specified value r. In this paper we have designed a cost-optimal (parallel)...
Vibrational energy harvesters (VEH) are increasingly becoming the favourite approach towards making self sustained low power systems. However, obtaining frequencies close to those of ambient vibrations has been a challenge. In the current work we have proposed a novel design of the piezoelectric-VEH (P-VEH) consisting of a micro-machined thick silicon proof mass suspended with quad-beams carved out...
These days, in emergency, multiple assay operations are required to be performed at parallel. Area of a given chip as a constraint, how efficiently we can use the chip and how much parallelism can be built-in are the objectives of this paper. A typical application of an assay may characterize a sample where, say only one type of reagent and multiple samples have been considered, or vice versa, and...
Vibration energy harvesting is gaining attention due to abundance of vibration energy at most places and ability to generate power MEMS devices from microwatts to few millwatts. Piezoelectric energy harvesters are the most suitable for vibration energy harvesting due to simplicity in design, operation and fabrication in MEMS technology. Cantilever fixed from one end and seismic mass on the free end...
