Clocking and clocked storage elements in a multi-gigahertz environment

摘要

Clocking considerations and the design of clocked storage elements are discussed in this paper. We present a systematic approach for deriving a clocked storage element suitable for “time borrowing” and absorption of clock uncertainties. We explain how to compare different clocked storage elements with each other, and discuss issues related to power consumption and low-power designs. Finally, results of comparisons among representative designs are presented.
