The spectrum intensity of the current of nonlinear resonance circuit driven by random and periodic voltages is investigated by solving two dimensional Langevin equations approximately, and the occurrence of a large current fluctuation is expected in a certain range of frequency. This phenomenon is also verified experimentally by observing the current noise in a nonlinear resonance circuit, which is composed of an ordinary inductance and a nonlinear capacitor made from ferroelectric tri-glycine sulphate.
