    摘要： A multi-mode driver and method therefore includes a plurality of amplifiers, an adjustable load block, and adjustable current supply circuitry that selectively adjusts current magnitudes supplied to at least one of the plurality of amplifiers. The multi-mode driver can operate in a KR mode with a higher voltage supply, an SR4 mode with the higher voltage supply, and an SFI mode with a lower voltage supply. To support these modes, the multi-mode driver selectively operates a plurality of amplifiers, adjusts current magnitudes supplied to the amplifiers, and selectively adjusts an adjustable load. Thus, the multi-mode driver is operable to selectively and efficiently produce high swing and low swing output signals and to efficiently operate with any one of a plurality of supplies. The driver includes selectable loads and parallel-coupled amplifier devices that are selected based on mode.

    摘要： Methods and apparatus for buffering RF signals. A method includes receiving an input signal, wherein the input signal alternates between a first polarity and a second polarity. From the input signal, a first current is generated, wherein the first current is proportional to the input signal when the input signal has the first polarity, and approximately equal to zero when the input signal has the second polarity, and a second current is generated, wherein the second current is proportional to the input signal when the input signal has the second polarity, and approximately equal to zero when the input signal has the first polarity. A third current is generated proportional to the first current, and a fourth current is generated proportional to the second current. The first and fourth currents are applied to a first terminal of an inductor; and the second and third currents are applied to a second terminal of the inductor.
