Abstract

An inductance device includes a first wiring, a second wiring, a third wiring, a fourth wiring, a first capacitor and a second capacitor. The first wiring includes at least two sub-wirings, and one end of the at least two sub-wirings is coupled to the first node. The second wiring includes at least two sub-wirings, and one end of the at least two sub-wirings is coupled to the second node. One end of the third wire is coupled to the second wire, and the other end of the third wire is coupled to the first input-output end. One end of the fourth wire is coupled to the first wire, and the other end of the fourth wire is coupled to the second input-output end. The first capacitor is coupled between the first node and the second node. The second capacitor is coupled between the first node and the first input-output terminal, or between the first node and the second input-output terminal, or between the first input-output terminal and the second input-output terminal.

Description

Technical field [0001] The present disclosure relates to an electronic device, and relates in particular to an inductive device. Background [0002] Radio frequency (RF) devices generate double-frequency harmonics (harmonic), triple-frequency harmonics when running... And so on, the above harmonics will have an adverse effect on the rest of the circuit. For example, the double-frequency harmonics of a 2.4GHz circuit produce a 5GHz signal and thus adversely affect the integrated circuit (SOC). [0003] The general solution to the effect of the above harmonics on the circuit is to set a filter outside the circuit to sense the high-frequency signal of adjacent components and can be designed to select the desired frequency and the frequency that does not need to be filtered. However, filters set outside the circuit can affect the performance of the circuit itself and additional costs, such as the cost of printing circuit boards (PCBs).
