Abstract
A system and method 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. A dynamic logic circuit has a runtime operation that alternates between an active and a passive mode and includes at least one transistor having a floating body and a threshold voltage level. A switching device within the dynamic logic circuit forms a means from which the floating body draws an electric charge during the passive mode, thereby altering the threshold voltage level. The switching device receives a clock input signal during the dynamic circuit's active mode. Input selection means selectively replace the clock input signal with a pre-clock input signal into the switching device for a pre-determined period of time prior to a transition by the dynamic logic circuit from the passive mode to the active mode, such that the floating body may adequately discharge, thereby initializing the threshold voltage level prior to commencement of the active mode.
