Abstract:
A system for initializing a threshold voltage level of a dynamic circuit prior to a transition of said dynamic circuit from a passive mode to an active mode, said system comprising:a dynamic logic circuit having a runtime operation that alternates between an active and a passive mode, said dynamic logic circuit including at least one transistor having a floating body and a threshold voltage level;a switching device within said dynamic logic circuit from which said floating body draws an electric charge during said passive mode, thereby altering said threshold voltage level, said switching device receiving a clock input during said active mode; andinput selection means for selectively replacing said clock input with a pre-clock input into said switching device for a pre-determined period of time prior to a transition by said dynamic logic circuit from said passive mode to said active mode, such that said floating body discharges, thereby initializing said threshold voltage level prior to commencement of said active mode.
