(a) Time-domain signal of waveform \(v_{{{\text{out}}}} \left( t \right)\) (red), amplitude \(v_{{{\text{amp}}}} \left( t \right)\) (blue), and input (black). (b) Examples of time evolutions of normalized orbit radius \(s\) under same measurement condition. These results were obtained under input condition of \(V_{1} = 80\)Â mV and \(V_{2} = 300\)Â mV.
