A differential inductor is formed from branch coils that are staggered with respect
to one another rather than concentrically coiled within one another. Each coil
is formed from conductive strips. The conductive strips with the largest voltage
swings thereon are shielded from one another by conductive strips with lower voltage
swings thereon. This shielding allows the effective capacitance of the differential
inductor to be lowered, which in turn raises the range of frequencies at which
the differential inductor can operate.
