Aspects of the disclosure are directed to a low noise T-coil design. In accordance with one aspect, an input/output (I/O) circuit includes a first T-coil, wherein the first T-coil includes a first set of two inductors connected to each other in series arranged to accommodate a first current flow to produce a first magnetic field with a first perpendicular direction; and a second T-coil, wherein the second T-coil includes a second set of two inductors connected to each other in series arranged to accommodate a second current flow to produce a second magnetic field with a second perpendicular direction; and wherein the second magnetic field cancels the first magnetic field.
