The System-On-Chip (SoC) design is integrating hundreds of millions of transistors on one chip, whereas packaging and cooling only have a limited ability to remove the excess heat. In this paper, various design techniques for a low power clocking system are surveyed. Among them is an effective way to reduce capacity of the clock load by minimizing number of clocked transistors. To approach this, we propose a novel clocked pair shared flip-flop which reduces the number of local clocked transistors by approximately 40%. A 24% reduction of clock driving power is achieved. In addition, low swing and double edge clocking, can be easily incorporated into the new flip-flop to build clocking systems.
