Abstract
The lumped equivalent circuit model of a superconducting tunnel junction with a voltage‐dependent normal conductance current represented by Ir = I0(V/V0)n is analyzed for the cases n = 2 and n → ∞. Analytic expressions for the hysteresis parameter as a function of the damping factor are obtained. The time‐averaged voltage‐current characteristics for n = 2 are given in closed form. The results are qualitatively similar to the linear conductance case where n = 1, but the hysteresis is more pronounced for larger n.Keywords
