Abstract

In this paper, an efficient pulse-shaping filter structure for high-density and low-power electronic devices is proposed. The proposed structure is based on polyphase decomposition property and look-up table method. By Synopsys CAD simulations, it is shown that the use of the proposed method can result in reduction in the number of gates by 54% and can reduce power consumption by 9%.

제안된 구조는 polyphase decomposition과 look-up 테이블 방식을 이용하였다. Synopsys CAD tool을 이용한 모의실험을 통하여 제안한 방식이 기존 방식에 비해 54% 정도의 게이트 수를 감소시킬 수 있고, 9% 정도의 전력소모를 줄일 수 있음을 보인다.
