Josephson Series Array Potentiometer

  • J. Niemeyer

Abstract

A Josephson tunnel junction which is operated at nonzero voltages produces an alternating supercurrent the frequency f of which is related to the dc voltage V across the junction by the simple equation:
$$V = (h/2e)f$$
(1.1)

h is Planck’s constant and e the elementary charge. (A detailed description of the Josephson effects is given in [1,2]). The validity of Eq. (1.1) is experimentally proved with extreme accuracy [3]. This makes a Josephson junction to be an ideal frequency to voltage converter.
