Design and Simulation of Flip Flop at 45 nm Technology for Application in WSN

Efficient power management in wireless sensor network is a critical issue as the sensor nodes are low powered devices. In a sensor node maximum power is consumed by microcontroller since most of the functionalities are controlled or performed by it. Flip flop occupies maximum areas of microcontroller. Hence, designing low power flip flop cells are highly important for prolonging the life time of network. This paper presents a simulation and comparative study of different flip flop cells for WSN applications based on simulation at 45nm technology. The simulation results show that flip flop using multiplexers offers the best overall performance.
