A true random number generator using write speed variation of oxide-based RRAM is proposed for the first time. The signal of this physical unclonable function (PUF) is strong with long duration to be easily and accurately captured by simple circuit, of which the advantage is attributed to the mechanism that the speed variation amplifies the fluctuation of oxygen vacancy trap and de-trap. Some function...
With the developing of power system, there many power plant of HUBEI JINGZHOU CHINA with small generation capacity interconnected with weak lines and more and more small capacity interconnected to power grid threaten the stability of power system. The small capacity system is not normally meet local load, and sometimes even larger shortage. Aimed at the different types of HUBEI JINGZHOU CHINA small...
A per-core clock generator for the eight-core POWER7™ processor is implemented with a digital PLL. This frequency generator is capable of smooth, controlled frequency slewing, minimizing the impact of di/dt. Frequency can be dynamically adjusted while the clock is running, and without skipping any cycles, thus enabling aggressive power management techniques.
The possible solution for electrifying rural areas of developing countries, where is far away from national grids, are off grid small hybrid systems using renewable energy. The photovoltaic(PV) hybrid system was installed in the village of Darsilami in Gambia and since December 2004 functions as a stand alone system that is used to supply electricity for a rural health clinic. All the generators are...
