수용 가능한 수준의 성능을 동시에 전달하고 분배하는 동안의 소비 전력을 줄이는 문제는 고성능 시스템의 설계분야에서는 더욱 더 결정 적 인 관심사로 받아지고 있다. 본 논문에서는 전력분배의 문제를 클럭 신호 발생과 분배의 관점에서 제시하고자 한다. 우리는 클럭 신호의 전력 효율성과 다른 응용제품 이외에도 무선통신의 회로에서도 찾아 검증하였다. The problem of reducing power dissipation while simultaneously delivering acceptable levels of performance is becoming a critical concern in high pelf[mann system design. In this paper, we present this power dissipation problem from the clock generation and distribution side. We examine clock power efficiency and several applications as well as wireless communication circuits.

A novel manufacturing method for hybrid composites filled with carbon nanotubes (CNTs) and aramid fibers is proposed. To disperse the CNTs in the epoxy matrix with the presence of aramid fibers, CNT/polyethyleneoxide (PEO) composites are prepared and utilized because PEO is miscible in the epoxy resin. After thin films are made of the CNT/PEO composite and placed together with the aramid fibers, the epoxy resin is infused to them. The PEO is dissolved in the epoxy and then the CNTs are dispersed in the PEO/epoxy matrix between aramid fibers before the pre-heated matrix is cured. It is found that the PEO is completely miscible with the epoxy resin and CNTs are dispersed well in the space between the aramid fibers.
