Apparatus and method for providing pre-emphasis to a signal |
| 摘要 |
A circuit including delay stages, gain stages, and a summer. The delay stages are configured to provide delayed versions of a first signal. The gain stages are configured to receive the delayed versions of the first signal. Each of the gain stages provides an amount of gain for a corresponding one of the delayed versions of the first signal. The delay stages and the gain stages are configured to provide pre-emphasis to the first signal. The summer is configured to output a second signal based on the delayed versions of the first signal. The second signal includes the pre-emphasis. |

1. A circuit comprising:
a plurality of delay stages configured to provide a plurality of delayed versions of a first signal; a plurality of gain stages configured to receive the plurality of delayed versions of the first signal, wherein each of the plurality of gain stages provides an amount of gain for a corresponding one of the plurality of delayed versions of the first signal, and wherein the plurality of delay stages and the plurality of gain stages are configured to provide pre-emphasis to the first signal; and a first summer configured to output a second signal based on the plurality of delayed versions of the first signal, wherein the second signal includes the pre-emphasis. |
