Abstract: An overview of clocking and design of clocked storage elements is presented. Systematic design of flip-flop is explained as well as "time borrowing" and absorption of clock uncertainties. We show how should different clocked storage elements be compared against each other. The issues related to power consumption and low-power design are presented.
Key words: Clocking, clock skew, clock jitter, clocked storage elements, flip-flop, master-slave, time borrowing.
