1. A one-coil multi-core inductor-capacitor (LC) oscillator, comprising:
a main coil, comprising:
an outer wire, coupled to a first core circuit and a second core circuit of the one-coil multi-core LC oscillator; and
a central wire, coupled between a first node and a second node of the outer wire;
wherein an outer loop formed by the outer wire corresponds to a first mode of the one-coil multi-core LC oscillator, and inner loops formed by the outer wire and the central wire correspond to a second mode of the one-coil multi-core LC oscillator; and
at least one mode suppression device, configured to suppress one of the first mode and the second mode, wherein the at least one mode suppression device comprises:
multiple resonance capacitors, configured to be coupled to the central wire for suppressing the second mode, in order to make the one-coil multi-core LC oscillator operate in the first mode.
