Abstract: A compensation apparatus including a primary circuit and a compensation circuit is provided. The primary circuit provides a first voltage, a second voltage, and a first current flowing through a first inductor. The primary circuit includes the first inductor and a function circuit generating an input signal. The first inductor is coupled between a first terminal with the first voltage and a second terminal with the second voltage. The compensation circuit includes a second inductor and a current source circuit. The second inductor is coupled between a third terminal with a third voltage and a fourth terminal with a fourth voltage. The current source circuit outputs a second current flowing through the second inductor. The current source circuit adjusts a frequency of the input signal. The primary circuit and the compensation circuit are coupled via the first inductor and the second inductor.

Abstract: A one-coil multi-core inductor-capacitor (LC) oscillator is provided. The one-coil multi-core LC oscillator includes a main coil and at least one mode suppression device. The main coil includes an outer wire and a central wire, wherein the outer wire is coupled to a first core circuit and a second core circuit, and the central wire is coupled between a first node and a second node of the outer wire. More particularly, 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, where the at least one mode suppression device is configured to suppress one of the first mode and the second mode.
