1. An inductor device, comprising:
a first trace, comprising at least two sub-traces, wherein one terminal of each of the at least two sub-traces are coupled to each other at a first node;
a second trace, comprising at least two sub-traces, wherein one terminal of each of the at least two sub-traces are coupled to each other at a second node;
a third trace, wherein the first trace and the third trace are disposed at a first side, wherein one terminal of the third trace is coupled to one of the at least two sub-traces of the second trace, and another terminal of the third trace is coupled to a first input/output terminal;
a fourth trace, wherein the second trace and the fourth trace are disposed at a second side, wherein one terminal of the fourth trace is coupled to one of the at least two sub-traces of the first trace, and another terminal of the fourth trace is coupled to a second input/output terminal;
a first capacitor, coupled between the first node and the second node; and
a second capacitor, coupled between the first node and the first input/output terminal, or coupled between the first node and the second input/output terminal, or coupled between the first input/output terminal and the second input/output terminal;
wherein each of the third trace and the fourth trace comprises at least two sub-traces, wherein each of the at least two sub-traces of each of the first trace, the second trace, the third trace and the fourth trace is U-typed trace.
