Yeah I thought that was the case from the diagrams. My brain has trouble with the concept of negative resistance.
Resistance is just impedance to DC, and impedance is derived from reactance (L and C).  Negative impedance/reactance is what you really want to measure. (sorry, there is just no way of avoiding the more painful AC math) Negative reactance can occur when capacitance or inductance is varied with respect to time. (This is how you would quantify the amount of energy produced in a parametric oscillator.) Assuming a lossless circuit in the above example and with all other factors being constant, the amplitude and frequency of oscillation will increase as L or C decrease. https://www.researchgate.net/publication/231003793_Parametric_resonance_in_a_linear_oscillator_at_square-wave_modulationThen there's also the possibility I have no idea what I am talking about
