DE-EMPHASIS CIRCUIT FOR A VOLTAGE MODE DRIVER USED TO COMMUNICATE VIA A DIFFERENTIAL COMMUNICATION LINK |
摘要 |
A circuit for de-emphasizing information transmitted via a differential communication link includes a voltage mode differential circuit and a bi-directional current source circuit. The voltage mode differential circuit includes a first and second output terminal. The voltage mode differential circuit provides a first voltage via the first output terminal and second voltage via the second output terminal in response to a differential input voltage. The bi-directional current source circuit is operatively coupled between the first and second terminals. The bi-directional current source circuit selectively provides current in a first and second direction between the first and second terminals based on the first and second voltage. |
