Patent ID: 7525407

Claim:
An integrated circuit comprising: at least one pair of transistors; at least one inductor group which includes a pair of inductors coupled to the at least one pair of transistors, respectively, the pair of inductors forming a spiral shape on a plane and the inductors arranged symmetrically to each other; and at least one pair of differential signal input terminals which are coupled to the at least one pair of transistors and to which differential signals are applied from the outside, wherein magnetic fluxes, which are generated by current flows along the inductors of the at least one inductor group, are formed in a direction to mutually intensify the magnetic fluxes according to the differential signals applied to the at least one pair of transistors via the at least one pair of differential signal input terminals, and wherein the at least one inductor group is at least one of a first inductor group which is coupled to gate terminals of the at last one pair of transistors with one end, a second inductor group which is coupled to source terminals of the at least one pair of transistors with one end, and a third inductor group which is coupled to drain terminals of the at least one pair of transistor with one end.
