Abstract
An integrated circuit is disclosed that includes one or more blocks of switching logic (comprised of transistors) connected between a power supply and a common node. A control transistor connects the common node to ground. The control transistor has a higher threshold voltage level than the voltage threshold level(s) of the transistors that comprise the switching logic blocks. A bias generator provides a positive bias to the body of the control transistor when the control transistor is 'on.' Further disclosed is an integrated circuit comprising a first plurality of serially connected transistors establishing a first current path from a voltage source to ground and a second plurality of serially connected transistors establishing a second current path from the voltage source to ground. The first and second plurality of transistors each includes at least one high-threshold transistor. The integrated circuit further includes a means for decreasing a resistance level of the high threshold transistors when the high threshold transistors are on.
