Nonlinear Circuit Analysis via Perturbation Methods and Hardware Prototyping

Figure 6

Magnitude-frequency response of unity-gain buffer. Analytical prediction is in bold, and experimental data is plotted as “x”s and “o”s. The fundamental harmonic is a low-pass filtered version of the input. The third harmonic has a bandpass shape, as predicted by perturbation analysis.
