Huge quantities of water are wasted on a daily basis worldwide because of leakages in water-transporting infrastructures causing water shortage, injuries, and so on. This problem is typically worsened by the lack of advanced monitoring systems. In this respect, wireless sensor networks (WSNs) have revolutionised water-monitoring systems providing reliable inspection, feasible communication and performing...
A 16-bit (5+11) segmented digital-to-analog converter (DAC), based on a voltage mode R-2R topology that is able to derive high resolution and high performance, in terms of INL and DNL, and less area and power consumption comparing with conventional DACs. It is designed and simulated in 65nm CMOS process. A current compensating technique is used to achieve good dynamic performance. The 16 bit R-2R...

Fixed-width multipliers are widely used in digital signal processing (DSP) applications such as finite impulse response filter (FIR), fast Fourier transform (FFT) and discrete cosine transform (DCT). Baugh-Wooley multiplier is a preferred choice for the realization of 2's complement multiplication operation used in these applications. This paper presents the hardware realization and performance evaluation...
As the flexibility offered by fine-grained field programmable gate array (FPGA) comes at a significant cost of area, speed, and power, there is a trend to use coarse-grained architecture (CGA) for dataflow applications requiring high computational resources. Existing CGA solutions are characterized according to the general organization, the processing element architecture, the basic interconnect structure...
