1. A circuit comprising:
a dual-port inductor comprising:
a first active component and a second active component, wherein each active component comprises a first terminal and a second terminal;
a first conductive microstrip comprising a first inductor portion and a second inductor portion electrically connected in series, wherein the first conductive microstrip electrically connects the first terminal of the first active component to the second terminal of the second active component;
a second conductive microstrip comprising a first inductor portion and a second inductor portion electrically connected in series, wherein the second conductive microstrip electrically connects the second terminal of the first active component to the first terminal of the second active component;
a coupling inductor comprising:
a first inductor portion; and
a second inductor portion,
wherein the first inductor portion, and the second inductor portion are electrically connected in series;
wherein the first inductor portion is magnetically coupled to the first or second inductor portion of the first conductive microstrip of the dual-port inductor, and the second inductor portion is magnetically coupled to the first or second inductor portion of the second conductive microstrip of the dual-port inductor, and
wherein the dual-port inductor and the coupling inductor are different inductors.
