Multi-Supply voltage design using Cluster Voltage Scaling (CVS) is an effective way to reduce power consumption without performance degradation. One of the major issues in this method is performance and power overheads due to insertion of Level Converting Flip-Flops (LCFF) at the interface from low-supply to high-supply clusters to simultaneously perform latching and level conversion. In this p...

Background: Controversial data concerning the elevation of serum angiotensin-converting enzyme in psoriasis are reported in the literature. In order to verify whether this abnormality exists in Iranian patients, we performed this study. Method: Serum angiotensin-converting enzyme level was measured in 40 psoriatics. According to clinical forms of psoriasis, patients were further divided into th...

Clustered Voltage Scaling (CVS) is an effective way to reduce power consumption in digital integrated circuits. Level-converting flip-flops are the critical elements in the CVS scheme. A single edge implicit pulse-triggered level-converting flip-flop with a conditional clock technique is used in the existing system. It increases the data switching activity due to longer delay. So the power cons...

In this paper, we propose the design of low power level-converting retention flip-flop (RFF)using LSSR technique for Zigbee System-onchips (SoCs).The proposed retention flip-flop allows the voltage regulator which generates the core supply voltage (VDD, core) is turned off during the standby mode and thus reduces the standby power and dc current of the Zigbee SoCs. This method is the combinatio...

objectives: the purpose of this experimental study was to evaluate the efficacy of low level laser therapy (lllt) for pain reduction after midpalatal expansion in rats.   materials and methods: sixty male sprague six-week old rats weighing 180±10g were divided into seven groups (two experimental groups of 24 rats and one control group of 12 rats). the experimental groups were subjected to expan...

Discrete cosine transform (DCT) is a widely compression technique for converting an image into elementary frequency components. However, level of quality and compression is desired, scalar multiples of the JPEG standard quantization may be used. In this paper, DCT method was applied to compress image under various level of quality. Different quantization matrices of DCT’s coefficients are used ...

Low scaling technology makes a significant reduction in dimension and supply voltage, and lead to new challenges about power consumption such as increasing nodes sensitivity over radiation-induced soft errors in VLSI circuits. In this area, different design methods have been proposed to low power flip-flops and various research studies have been done to reach a suitable hardened flip-flops. In ...
