1. A method of calibrating performance of a multi-fingered device within an integrated circuit (IC), the method comprising:
- determining a measure of degradation for the multi-fingered device within the IC, wherein a first finger of the multi-fingered device is active and a second finger of the multi-finger device is initially deactivated;
comparing the measure of degradation with a degradation threshold; and
responsive to determining that the measure of degradation meets the degradation threshold, activating the second finger of the multi-fingered device by coupling a gate of the second finger to a data signal also coupled to a gate of the first finger.

Abstract
A multi-fingered device can be calibrated for performance. The multi-fingered device can include a first finger configured to remain active and a second finger that is initially deactivated concurrent with the first finger being active. A measure of degradation for the multi-fingered device within an IC can be determined. The measure of degradation can be compared with a degradation threshold. Responsive to determining that the measure of degradation meets the degradation threshold, a finger of the multi-fingered device can be activated.

7. A multi-fingered device for implementation within an integrated circuit, the multi-fingered device comprising:
-
a first finger configured to remain active; a second finger that is initially deactivated concurrent with the first finger being active, wherein the second finger is configured for activation during operation of the integrated circuit; and a switch coupled to the second finger, wherein the switch selectively couples a gate of the second finger to a data signal also coupled to a gate of the first finger. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A system configured for implementation within an integrated circuit, the system comprising:
-
a multi-fingered device comprising a first finger configured to remain active and a second finger initially configured to be inactive concurrent with the first finger being active; a switch coupled to a gate of the second finger, wherein the switch is configured to activate the second finger by coupling a gate of the second finger to a signal also coupled to a gate of the first finger and deactivate the second finger by decoupling the gate of the second finger from the signal; and a finger activation circuit configured to instruct the switch to activate the second finger responsive to detecting a minimum amount of degradation in the device. - View Dependent Claims (17, 18)
