Abstract
A system and method are provided for providing an impedance match of an output buffer to a transmission line without significantly increasing the power consumption of the output buffer. A system and method are also provided for providing an impedance match of an output buffer to a transmission line, while still allowing for an adjustable output swing as is required for loads such as laser transmitters and optical modulators.
