摘要： In certain aspects, a circuit for multi-mode calibration can include a resistor input. The circuit can also include a first comparator connected to the resistor input and to a first plurality of voltage sources. The circuit can also include a first pull-up driver. The circuit can further include a logic pull-up code generator to calibrate the first pull-up driver. The circuit can additionally include a replica of the first pull-up driver. The circuit can also include a first pull-down driver and a second comparator connected to the replica, the first pull-down driver, and a second plurality of voltage sources. The second comparator can compare a voltage of a middle point between the first pull-down driver and the second pull-up driver to one of the second plurality of voltage sources. The circuit can further include a logic pull-down code generator.
