<p>A boost circuit (200) is configured to supplement a drive current provided by the drivers on a computer backplane. When the driverdrives the signal to pass a lower threshold (224), the boost circuit engages to drive a current larger than the driver current provided by the driver to switch the signal above an upper threshold (226) more quickly. When the signal passes the upper threshold (226), the boost circuit disengages and the driver suitably maintains the signal at the higher level. As the driver then starts to drive the signal negative, once the signal again passes the upper threshold (226), the boost circuit engages to drive a current larger than the drive current provided by the driver to switch the signal below the lower threshold (224) more quickly.</p> |
