碩士 === 國立交通大學 === 電子研究所 === 84 === Low-voltage low-power integrated circuits are essential in portable electronic systems. In this thesis, two new high- speed dynamic current-sensing digital logic circuits are proposed and investigated. One is the current-sensing true- single-phase-clock CMOS logic (CSTSPC), the ot> is the current-sensing true-four-phase-clock CMOS logic (CSTFPC). These two new dynamic logic circuits are suitable for the applications in low-voltage low-power systems. Since the current-sensing scheme can yield a fast sensing speed than the conventional voltage-sensing scheme under 1.2 volt low-voltage operation node and the dynamic current-sensing scheme has no dc power dissipation. Based upon the principles, our two new high-speed dynamic current-sensing digital logic circuits (CSTSPC,CSTFPC) can achieve two times faster than the conventional true-single- phase CMOS logic (TSPC), conventional true-four-phase CMOS logic (TFPC) and have smaller power-delay product.
