Disclosed is a chaotic oscillator comprising a first nonlinear function unit to which an output of a level shifter is fed back; and a second nonlinear function unit to which an output of the first nonlinear function unit and the output of the level shifter are fed back. The output of each of the first nonlinear function unit and the second nonlinear function unit is calculated by applying a nonlinear function to the output of the level shifter, and the level shifter outputs a chaotic signal based on the output of the first nonlinear function unit and the output of the second nonlinear function unit. |
