Abstract
A signal coupling method and apparatus is disclosed. A coupling network is coupled to convey signals from first functional circuit block to a second functional circuit block. The coupling network includes a first signal path having a first capacitor for providing AC coupling between the first and second functional circuit blocks. The coupling network further includes a second signal path in parallel with the first signal path. The second signal path includes a switched capacitor circuit coupled to receive a first common mode voltage corresponding to the first functional circuit block and a second common mode voltage corresponding to the second functional circuit block.
