Abstract
Devices and methods are described herein for a pulse amplitude modulation (PAM) driver. In one embodiment, the PAM driver includes a first high-speed buffer configured to output a first voltage, a second high-speed buffer configured to output a second voltage, and a plurality of transistors coupled to the first high-speed buffer and the second high-speed buffer. At least one of the first voltage or the second voltage facilitates selective operation of a transistor of the plurality of transistors to output a third voltage.
