Abstract: An oscillator is provided. The oscillator includes two reverse amplification elements, and each of the reverse amplification elements forms a self-feedback structure by using an inductor. Output ends of the two reverse amplification elements are coupled to each other by using one or more inductors, and input ends of the two reverse amplification elements are coupled to each other by using a capacitor. A capacitance value of the capacitor may be adjusted, to change an oscillation frequency of a differential output oscillation signal output by the oscillator.

Abstract: This application provides an inductor, an oscillator, and a terminal device, and relates to the field of inductor technologies. The inductor includes one primary conductive segment, at least two first conductive sub-segments, and at least one switch. Two ends of the primary conductive segment are respectively connected to two primary ports. At least two taps are disposed on the primary conductive segment. One end of the first conductive sub-segment is connected to one of the taps, and the other end of the first conductive sub-segment is connected to one tap port. The at least one switch includes a first switch disposed between the at least two taps, and/or a second switch disposed on any one or more of the first conductive sub-segments.
