Eg. Fundamental is 5 MHz & you get harmonics at 10 MHz, 20MHz, etc.
How is the diode’s non-linearity causing this? I can’t find a way to visualize it.
In: 10
A diode’s IV curve can be modeled as an exponential. So a change in voltage about the bias point will result in a change in current. However, that same change in voltage about a higher voltage point will result in a larger change in current. Overall, this behavior squishes peaks and accentuates low values (appears to bring everything towards a central value). This results in a more square wave.
