A critical issue in wireless sensor networks is the limited availability of power and hence optimizing power is very important. In any sensor node, transitions from idle to busy state and vice versa consume most of the power. We propose a new scheme to reduce the power consumption of nodes by reducing the number of transitions of the sensor node based on the number of packets in the queue i.e.,...

Abstract: Power consumption is considered as one of the important challenge in modern VLSI design along with area and speed consideration. Flip flop plays very important role in digital systems. In this paper comparative study of four different flip flops which includes pulse triggered as well as conditional technique flip flop such as IP-DCO, MHLFF, CPSFF, and CPFF topologies in sub threshold ...

A rapid growth in semiconductor technology and increasing demand for portable devices powered up by battery has led the manufacturers to scale down the feature size, resulting reduced threshold voltage and thereby enabling integration of extremely complex functionality on a single chip. In CMOS circuits, increased sub-threshold leakage current refers static power dissipation is the result of lo...

Kerr optical frequency combs have found various applications in science and technology, minimizing their pump power has become an important area of research. These are generated using a wide variety platforms, with size ranging from micrometers to millimeters, quality factors millions billions. It is therefore not trivial assess the requirements for comb generation when they such large diversit...

Level shifters play critical roles in ultra low-voltage circuits and systems. a new low power level shifter (LS) is presented for robust logic voltage shifting from near/sub threshold to above threshold domain. The new circuit combines the multi threshold CMOS technique along with novel topological modifications to guarantee a wide voltage conversion range with limited static power and total en...
