ABSTRACT:
This disclosure is directed to techniques for reducing erroneous static logic signals when logic signals change relative to a clock signal within a dynamic to static logic converter circuit. Domino logic circuits, for example, utilize dynamic logic signals evaluated relative to a clocking signal. When dynamic logic signals are evaluated, logic signals propagate within logic circuits. Dynamic to static logic converter circuits possess logic signals used to generate static logic signals that change state at well defined points in time relative to a clocking signal used by dynamic logic. Use of a delay for a clocking signal by a latch circuit utilized to capture a dynamic logic signal for conversion to a static logic signal reduces logic level changes in static logic signals during times in which dynamic logic signals may be indeterminate. Use of current limiting circuit elements associated with the latch circuit may further reduce logic level changes during these times in which dynamic logic signals may be indeterminate.
