This means the equivalent circuit for an RF capacitor would function as shown in the model below. Capacitor circuit model that is used at high frequencies. Here we have the standard set of parasitic elements that appear in the typical capacitor model (ESR and ESL); these determine a capacitor''s impedance curve and its self-resonant frequency.
But if you want your capacitor to vary according to V(external), you have to do one of two things: 1) integrate V(external) first, so that its derivative will be V(external), itself, or 2) use Q=x*V(external), which makes LTspice differentiate "x", only, leaving V(external) to be the actual value of the capacitance.
