| 摘要 |
A system and method for generating a clock signal is disclosed. In various embodiments of the invention disclosed herein, a global clock signal is generated and provided as an input to local clock circuitry operable to generate a local clock signal therefrom. The local clock circuitry comprises logic components that are susceptible to negative bias thermal instability (NBTI) effects resulting in degradation of the local clock signal. Clock propagation adjustment circuitry is used to modify the duty cycle of the global clock signal to compensate for the degradation resulting from NBTI effects thereby providing an optimized local clock signal.
