Abstract:
Techniques are described for ground-intermediating buffering that can effectively use the reference grounds of the circuit domains on either side of a buffer stage to generate one or more intermediated grounds for one or more signal buffers. For example, one of the reference grounds has a first amount of ground noise, the other of the reference grounds has a second amount of ground noise that is greater than or less than the first amount, and the intermediated grounds are generated to have respective amounts of ground noise that are between the first and second amounts. The ground intermediating buffer can perform signal buffering with respect to the intermediated ground(s), thereby reducing ground noise coupling across the circuit domains through both the signal and ground paths of the buffer stage.
