SELF-TUNING OF SIGNAL PATH DELAY IN CIRCUIT EMPLOYING MULTIPLE VOLTAGE DOMAINS |
摘要 |
Circuits and methods provided in multiple voltage domains that include self-tuning or timing of a signal path are disclosed. A plurality of paths is provided in the circuit. Each path traverses a portion of the multiple voltage domains, which may include any number or combination of the multiple voltage domains. Each of the paths has a delay responsive to at least one of the plurality of voltage domains. A delay circuit is provided and configured to generate a delay output related to the delay in the plurality of paths. In this manner, the delay output of the delay circuit is self-tuned or adjusted according to the delay in the plurality of paths. This self-tuning may be particularly suited to control the delay of a first signal path relative to a second signal path wherein the delay in the paths can vary with respect to each other during operation. |
