SELF-TUNING OF SIGNAL PATH DELAY IN CIRCUIT EMPLOYING MULTIPLE VOLTAGE DOMAINS

摘要

in the signal path, self-circuits and methods are provided in multiple voltage domains, including the tuning or timing are disclosed. A plurality of paths are provided in the circuit. Each of the path traverses a portion of the multiple voltage domain, which may comprise any number or combination of the multiple voltage domain. Each of the path has a delay in response to at least one of the plurality of voltage domain. The delay circuit is configured to generate a delayed output is provided to a delay involved in a plurality of paths. In this way, the delayed output of the delay circuit according to the delay itself in a plurality of path-tuning or adjustment is. This self-tuning is also used to control the delay of the first signal path to the second signal path, particularly suitable, wherein, in the path of the delay can be varied relative to one another during operation
