Patent ID: 7816742

Claim:
An integrated circuit including: a first plurality of n-type active devices configured to accept a first n-type body biasing voltage; a first plurality of p-type active devices configured to accept a first p-type body biasing voltage; a second plurality of n-type active devices configured to accept a second n-type body biasing voltage; a second plurality of p-type active devices configured to accept a second p-type body biasing voltage; wherein the body terminals of the first plurality of n-type active devices and the body terminals of the first plurality of p-type active devices and the body terminals of the second plurality of n-type active devices and the body terminals of the second plurality of p-type active devices are configured to be electrically isolated from one another; wherein the first plurality of n-type active devices and the first plurality of p-type active devices are operable to operate at an increased frequency in response to the first plurality of n-type active devices and the first plurality of p-type active devices receiving body bias compared to an unbiased condition; and wherein the second plurality of n-type active devices and the second plurality of p-type active devices are operable to operate at a decreased upper frequency limit in response to the second plurality of n-type active devices and the second plurality of p-type active devices receiving body bias compared to an unbiased condition.
