Abstract

In this paper, a new four-phase dynamic logic, called the high-speed precharge-discharge CMOS logic (HS-PDCMOS logic) is proposed and analyzed. Basically the HS-PDCMOS logic uses two different units to implement the logic function and to drive the output load separately. Thus a complex function can be implemented within a single gate and achieve a high operation speed. The HS-PDCMOS logic needs four operation clocks and has three different versions. An experimental chip has been designed and measured to verify partly the results of circuit analysis and simulation. It is shown that the HS-PDCMOS has an operation speed about 2.5 to 3 times higher than the conventional four-phase dynamic logic. Moreover, the new logic has no problems of clock skew, race, and charge redistribution.
