Line impedance calibration using actual impedance determination |
摘要 |
An approach for impedance matching a transmission line includes using the actual line impedance. According to one example embodiment, the impedance of a line connecting first and second nodes is calibrated by first driving the line to a steady-state voltage using a first current having a magnitude greater than zero, driving the current to a zero magnitude from the first node and therein inducing a voltage transient. The resultant voltage level on the line at the first node is then measured and analyzed relative to a reference voltage. The result of the comparison is then used to adjust the conductance at the second node.
