ABSTRACT:
The present invention provides a system for controlling performance of a switch transistor (106)—one that is implemented within a circuitry segment (100) to shut off a circuitry component (116) when that component is not in use. The switch transistor has a first terminal coupled to a first supply voltage (102), a second terminal coupled to an internal voltage rail (108), a gate coupled to an activation signal source (110), and a body coupled to a bias signal source (114). A bias signal, sufficient to induce a negative body bias across the switch transistor, is applied by the bias signal source when that transistor is shut off. A bias signal, sufficient to induce a negative body bias across the switch transistor, is applied by the bias signal source for a period of time following assertion of an activation signal from the activation signal source that turns the switch transistor on. A bias signal, sufficient to induce a positive body bias across the switch transistor, is applied by the bias signal source after the period of time.
