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.
