Abstract: An interface circuit, comprising: a signal line having signal, auxiliary and connection nodes defined therealong, the connection node for connection to a transmission line; signal-handling circuitry connected to the signal line at the signal node; an auxiliary circuit connected to the signal line at the auxiliary node; a signal pair of inductors connected in series along the signal line adjacent to and either side signal node; and an auxiliary pair of inductors connected in series along the signal line adjacent to and either side of the auxiliary node, wherein: the signal pair of inductors are configured to have a mutual coupling defined by a coupling coefficient kS; the pair of inductors are configured to have a mutual coupling defined by a coupling coefficient kA; and kS has a positive value and kA has a negative value.
