Comparison of Conditional Internal Activity Techniques for Low Power Consumption and High Performance Flip-Flops
This paper reviews the three Conditional internal activity Techniques for high performance flip-flops namely Conditional Capture, Conditional Pre-charge and Conditional Discharge techniques. These techniques are reviewed in terms of power and delay and classified based on how to prevent or reduce the internal switching activity. Application of the Conditional techniques results in improvement of Energy-Delay product and saving of power consumption for quiet input. Low power flip-flops are vital for the design of low-power digital systems. In this paper low power high performance flip flops are reviewed based on these techniques. Comparison summary of recent results of flip-flop characteristics based on these techniques is also specified.
