Abstract
A method for controlling an IC having logic cells and a clock-tree cell. Each logic cell has first and second FETs, which are pMOS and nMOS respectively. The clock-tree cell includes third and fourth FETs, which are pMOS and nMOS respectively. The clock-tree cell provides a clock signal to the logic cells. A back gate potential difference (“BGPD”) of a pMOS-FET is a difference between its source potential less its back-gate potential, and vice versa for an nMOS-FET. The method includes applying first and second back gate potential difference (BGPD) to a logic cell's first and second FETs and either applying a third BGPD to a third FET, wherein the third BGPD is positive and greater than the first BGPD applied, which is applied concurrently, or applying a fourth BGEPD to a fourth FET, wherein the fourth BGPD is positive and greater than the second BGPD that is applied concurrently.
