Abstract
A driver includes a first driver stage having at least one input node and at least one first output node. The first driver stage includes a T-coil structure that is disposed adjacent to the at least one first output node. The T-coil structure includes a first set of inductors each being operable to provide a first inductance. A second set of inductors are electrically coupled with the first set of inductors in a parallel fashion. The second set of inductors each are operable to provide a second inductance. A second driver stage is electrically coupled with the first driver stage.
Claims20
A driver comprising:
- a first driver stage having at least one input node and at least one first output node, the first driver stage including a T-coil structure that is disposed adjacent to the at least one first output node, the T-coil structure comprising:
- a first set of inductors each being operable to provide a first inductance;
- and
- a second set of inductors electrically coupled with the first set of inductors in a parallel fashion, wherein the second set of inductors each are operable to provide a second inductance;
- and
- a second driver stage that is electrically coupled with the first driver stage.
A driver comprising:
- a first driver stage having at least one input node and at least one first output node, the first driver stage including a T-coil structure that is disposed adjacent to the at least one first output node, wherein the T-coil structure comprises:
- a first set of inductors each being operable to provide an inductance of about 0.2 nanohenries (nH) or more and a coupling coefficient of about 0.5;
- and
- a second set of inductors electrically coupled with the first set of inductors in a parallel fashion, wherein the second set of inductors each are operable to provide an inductance of about 0.2 nH or more;
- and
- a second driver stage that is electrically coupled with the first driver stage.
A driver comprising:
- a first driver stage having first and second input nodes and first and second output nodes, the first driver stage including T-coil structures each being disposed adjacent to the first output node and the second output node, the T-coil structures each comprising:
- a plurality of sets of inductors that are electrically coupled with each other in a parallel fashion, wherein each set of the inductors is operable to provide a coupling coefficient of about 0.5;
- and
- a second driver stage having third and fourth input nodes, wherein the third input node is electrically coupled to the first output node and the fourth input node is electrically coupled to the second output node.
