Design of sequential elements for low power

  1. 1. Design of Sequential Elements for Low Power Clocking System AIM: The main aim of the project is to design “Design of Sequential Elements for Low Power Clocking System”. (ABSTRACT) Power consumption is a major bottleneck of system performance and is listed as one of the top three challenges in International Technology Roadmap for Semiconductor 2008. In practice, a large portion of the on chip power is consumed by the clock system which is made of the clock distribution network and flopflops. 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 Proposed Method: In this architecture the proposed CPSFF consume less power than CDMFF. Further we can apply low power techniques to reduce static power. In these low power techniques the extra circuit added to existing circuit even the power is reduced.

  2. 2. Advantage: The proposed multiband flexible divider also uses an improved loadable bit-cell for Swallow-counter and consumes a power of 0.96 and 2.2 mW in 2.4- and 5-GHz bands, respectively, and provides a solution to the low power PLL synthesizers for Bluetooth, Zigbee, IEEE 802.15.4, and IEEE 802.11a/b/g WLAN applications with variable channel spacing.
