| Popis: | The proximity effect as well as the roughness of the conductor can increase the conductive loss in differential lines. A trench structure design introduced in [1] has been shown to reduce the negative effects of the proximity effect, however calculating the differential impedance of such structure is not straightforward. In this work, a methodology based on Schwartz-Christoffel transformation is discussed and introduced to ease the derivation of an analytical description of the differential impedance of the trench lines. The results show that the analytical calculation is much faster than the numerical counterpart and produces errors below 10% for a large number of possible cases. It is also shown that for the practical and manufacturable structures the error can be kept below 5%. |
