Pseudo dynamic logic (SDL): a high-speed and low-power dynamic logic family
نویسندگان
چکیده
In this paper, a new logiedesign style called Pseudo Dynamic Logic (SDL) is introduced. In this logiedesign style, the internal nodes of the logic circuits are not precharged to high or low values, rather the initial charges on nodes are shared to yield an intermediate precharge value for faster evaluation. A 32-bit adder has been designed and simulated using HSPICE Level-49 parameters of a 0 . 6 ~ CMOS process. Simulated measurements on this adder show that the worst-case delay is 1.5611s. This demonstrates 2.1 times speed improvement in comparison to a domino dynamic logic design implemented with the same technology.

Low-Power Data-Driven Dynamic Logic (DL)
In this paper a new family of low-power dynamic logic called Data-Driven Dynamic Logic (DL) is introduced. In this logic family, the synchronization clock has been eliminated, and correct sequencing is maintained by appropriate use of data instances. Then, it is shown that replacement of the clock with input data implies less power dissipation without speed degradation compared to conventional ...
