Patent ID: 8111098

Claim:
An apparatus for amplifying a signal, the apparatus comprising: a signal input; a signal output; and an output driver connected between the signal input and the signal output, the output driver comprising: a plurality of driver segments connected in parallel, each having an input connected to the signal input and each having an output; a plurality of series capacitors, each associated with one of the plurality of driver segments, wherein the plurality of series capacitors is each connected between the output of its associated driver segment and the signal output; and a plurality of shunt capacitors, each associated with one of the plurality of driver segments having an associated series capacitor, wherein the plurality of shunt capacitors is each connected between the output of its associated driver segment and a ground; a plurality of transmission gates, each connected between the signal input and one of the plurality of driver segment inputs, wherein the transmission gates are adapted to activate and inactivate a driver segment to which it is connected.
