==Original Abstract Submitted==

A post-driver with low voltage operation and electrostatic discharge protection is provided. A post-driver structure includes a drive unit including a pull-up driver and a pull-down driver, a pad connected to an external resistance, and an output node connected between the pull-up driver and the pull-down driver. The output node is configured to connect to a comparator for impedance calibration of the drive unit. The post-driver structure also includes an operational amplifier connected to a first transistor and the pad in a closed loop configuration. The operational amplifier is further connected to a second transistor to form a current mirror circuit between the operational amplifier and the drive unit. The current mirror circuit replicates a voltage at the pad with a voltage at the output node for the impedance calibration.
