Method for Ensuring Accurate AC Waveforms with Programmable Josephson Voltage Standards

June 1, 2013
Author(s)
Charles J. Burroughs, Alain Rufenacht, Samuel Benz, Paul Dresselhaus
The amplitudes of stepwise-approximated sine waves generated by programmable Josephson voltage standards (PJVS) are not intrinsically accurate because the transitions between the quantized voltages depend on numerous conditions. We have developed a method
