Abstract :
The behavior of a non-hysteretic shunted Josephson junction can be described by a differential equation admitting analytical solution in the constant current bias case. Studying the pulse bias as a sequence of constant bias states we were able to derive expressions for the phase lock condition and study some relevant features of Shapiro steps.
