Patent ID: 7592879

Claim:
An integrated circuit having at least one integrated transmission line for the transmission of a high-frequency differential signal, the integrated circuit comprising: at least two series-connected line arrangements, each of which has a differential input, a differential output, a first trace connected to a first terminal of the differential input and a first terminal of the differential output, and a second trace connected to a second terminal of the differential input and a second terminal of the differential output, wherein each line arrangement has at least two crossing regions in which the first and the second traces cross, and wherein each line arrangement has at least four positive feedback regions, in which at least one first section of the first trace is placed at a first distance to at least one second section of the second trace in such a way that the magnetic fields, caused by currents flowing in the first and section sections, are mutually amplified in the exterior space surrounding the first and second sections when the high-frequency differential signal is applied at the differential input of the line arrangement.
