Research paper thumbnail of A new leakage reduction method for ultra low power VLSI design for portable devices

Power, Control and Embedded Systems (ICPCES), 2012 2nd International Conference, Dec 19, 2012

These devices require charging after a certain amount of usage time. Most of the time during discharging cycle, they remain idle or inactive. If these devices are not in active use, why does the battery discharge? The answer is leakage power consumption. At present the power density in CMOS integrated circuits has increased due to combination of higher clock speeds, greater functional integration, and smaller process geometries. With downward scaling of technology, static power consumption is becoming more dominant. It is challenging for the circuit designers to balance both scaling and low static power demands. In this paper, we propose a new method to reduce static power in the CMOS VLSI circuit using stacked sleep transistor without being penalized in power delay product requirement and circuit performance.

between static power consumption and technology scaling. Recently, the power density has increased due to combination of higher clock speeds, greater functional integration, and smaller process geometries. As a result static power consumption is becoming more dominant. This is a challenge for the circuit designers. However, the designers do have a few methods which they can use to reduce this static power consumption. But all of these methods have some drawbacks. In order to achieve lower static power consumption, one has to sacrifice design area and circuit performance. In this paper, we
propose a new method to reduce static power in the CMOS VLSI circuit using Variable Body Biasing technique without being penalized in area requirement and circuit performance

Research paper thumbnail of A comparative study of rooftop micro wind turbines on Bangladesh perspective

Power, Control and Embedded Systems (ICPCES), 2012 2nd International Conference , Dec 19, 2012

Development of micro wind turbines are now enabling us to utilize the wind resources in urban areas and hence providing a great opportunity for the developing countries with low wind resources to meet up their increasing energy demand. In our work, we have analyzed the performance of some popular micro wind turbines from the perspective of Bangladesh. Detailed analysis has been performed to find out the generation capability and system output. The choice of an effective turbine has been suggested and also the feasibility of the turbines has been analyzed from an economic point of view. Finally, suggestions for future development of hybrid and smart systems have been presented.
