Abstract: A driver circuit device using driver equalization in power and ground terminated transmission line channels. The driver circuit device can include a weaker pull-up driver, which is needed to pre-emphasize the pull-up signal for driver equalization in power terminated transmission line channels. The driver circuit device can also include a weaker pull-down driver, which is needed to pre-emphasize the pull-down signal for driver equalization in ground terminated transmission line channels. In the transmission line channels with power terminations, a weaker pull-up Ron is implemented. In the transmission line channels with ground terminations, a weaker pull-down Ron is implemented. Drivers implemented in power and/or ground terminated transmission line channels can be used to improve device performance, such as in signal eye opening.
