Abstract
A semiconductor device may include one or more output drivers. An output driver may be adjusted for impedance matching by applying a body voltage to one or more transistors of the output driver. In some examples, the body voltage applied may be based on a comparison between a reference voltage and a voltage at an external terminal. In some examples, the semiconductor device may include a calibration circuit that includes a comparator and an up/down counter that, based on a signal from the comparator, generates a code indicating the body voltage to be applied. The body voltage may be applied by a voltage generator in some examples.
