HP memristor I-V loop: V(t) = (R_on x + R_off(1-x))·i(t), pinched at origin

HP memristor I-V characteristic: V(t) = M(x(t))·i(t) with memristance M(x) = R_on·x + R_off·(1−x) interpolating linearly between R_on (at x=1) and R_off (at x=0). Key signature: V = 0 whenever i = 0, independent of x — the I-V curve is…
