ABSTRACT:
A method and apparatus for dynamically providing an AC termination for a signal bus going to a connector. A circuit is provided that senses whether the connector is occupied. If the connector is un-occupied, an AC termination circuit is dynamically enabled to provide appropriate termination of the signal bus. If the connector is occupied, the AC termination circuit is dynamically disabled so that the signal bus has no termination at the connector. The circuit has application in a personal computer.
