US Patent 6933744 Low-leakage integrated circuits and dynamic logic circuits

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.”
