APPARATUS AND METHOD FOR BIAS COMPENSATION IN DIFFERENTIAL TRANSMISSION LINES |
摘要 |
<p>A transmission line circuit includes a line driver having first and second outputs coupled through a differential transmission line to first and second inputs of a line receiver. A first bias is provided between the first and second inputs of the line receiver. The second bias is applied between the first and second outputs of the line driver. As a result, the first and second biases substantially offset, and preferably cancel, each other. If the differential transmission line is not coupled to a line driver, the second bias associated with that line driver is not applied permitting the first bias to provide a relatively high noise margin.</p> |
