The objective of this paper is to design a Low-Voltage, Low-Power and High-Gain Operational Amplifier used for high speed compensated CMOS op-amp which specifies open loop circuit parameters to obtain enhanced gain, settling time and closed loop stability An Op-Amp is designed in a 0.18 μm standard digital CMOS Technology The low noise high speed Op-Amp is designed using 180nm CMOS technology a...

We describe the operational principles of a scalable hardware accelerator for volume rendering. The basic philosophy is to provide an atomic unit which already provides sophisticated volume graphics at interactive rendering speed. Realtime speed can then be achieved by operating multiple units in par­ allel. The basic unit consists of just four VLSI chips and the volume memory and thus meets th...

High-speed low-power matched filter plays an important role in the fast despreading of spread-signals in wideband code division multiple access (W-CDMA) mobile communications. In this paper, we describe the algorithm and the VLSIarchitecture of a complex matched filter chip implemented by our proposed digital-controlled analog parallel operational circuits. The complex matched filter VLSI with ...

The effect of pH, agitation speed and coagulant dosage on the coagulation performance of aluminium sulfate with respect to the treatment of Medjerda water was investigated in this paper. The measurement of residual aluminium speciation was also conducted. The evaluation of treatment efficiency of the optimization of coagulation process while was determined by measuring the reduction of turbidit...

With 900 Autonomous Underwater Vehicles (AUVs) required over the next decade (Newman et al., 2007) existing survey-style AUVs need improved utilization factors. Additional control devices to extend operational capability need consideration together with the interchange between AUV control approaches. This paper considers supplementary through-body tunnel thruster control during the transition f...

The UK has an abundant offshore wind resource with offshore wind set to grow rapidly over the coming years. Optimisation of energy production is of the utmost importance given the high installation and maintenance costs of offshore turbines; accurate estimates of wind speed characteristics are critical during the planning process. While operational assessment methods which rely upon in-situ obs...

Dedicated hardware can be used to release the CPU of an image processing system, of routine image pro-processing tasks, thereby speeding up the operational speed of the system. This paper describes the hardware implementation of a one-pass fill, shrink and expand algorithm to clear random noise from an image. The three operations, comprising the algorithm, operate in parallel on a raster-scan i...

objective: to systematically identify the various methods of speed management and their effects. methods: a systematic search was performed in science direct, ovid medline, scopus, pubmed and proquest databases from april to june 2015. hand searching and reference of selected articles were used to improve article identification. articles published after 1990 which had reported on efficacy/effec...

present study is an extension of earlier work carried out on two-lane two way roads in the two provinces of pakistan i.e. n-25, n-55 and n-5 regarding the measure of operating speed and development of operating speed prediction models. curved sections of two-lane rural highways are the main location of run-off road accidents. in addition to that the road alignment having combination of geometri...

This paper presents new recursive dynamics algorithms that enable operational-space control of floating-base systems to be performed at faster rates. This type of control approach requires the computation of operational-space quantities and suffers from high computational order when these quantities are directly computed through the use of the mass matrix and Jacobian from the joint-space formu...
