Abstract
A driver having a switchable gain including a first circuit connected to a potential source, an input node receiving an input current, and an output node and operable in both low and high transmission frequency modes, and a second circuit connected to the potential source and a node of the first circuit and operable in only the high transmission frequency mode. In the low transmission frequency mode, the potential source is at a first level and the first circuit receives the input current and provides a first output current with a first current gain to the output node. In the high transmission frequency mode, the potential source is at a second, lower level and the first and second circuits receive the input current and provide a second output current, less than the first output current, with a second current gain, lower than the first current gain, to the output node.
