Abstract: A driver of a multi-level signaling interface is provided. The driver may be configured reduce noise in a multi-level signal (e.g., a pulse amplitude modulation signal) generated by the driver using switching components of different polarities. The driver may include a pull-up circuit and/or a pull-down circuit. The pull-up circuit and the pull-down circuit may include at least one switching component of a first polarity (e.g., nmos transistor) and at least one switching component of a second polarity different from the first polarity (e.g., pmos transistor). Such a configuration of pull-up and pull down circuits may generate a more linear relationship between an output current and an output voltage of an output of the driver, thereby improving one or more characteristics of the multi-level signal.
