Improved transient response of controllers by synchronizing the modulator with the load step: application to v2ic [PDF]

open access: yes, 2015
V2Ic is a ripple-based control with an excellent performance for load transients and reference voltage tracking because it exhibits a feedforward of the load current and the error of the output voltage.

Model $I$--$V$ curves and figures of merit of underdamped deterministic Josephson ratchets

open access: yes, 2016
We propose simple models for the current-voltage characteristics of typical Josephson ratchets. We consider the case of a ratchet working against a constant applied counter force and derive analytical expressions for the key characteristics of such a ...
