Abstract :
Synthesizing Josephson stepwise sine waves to produce an AC quantum standard is limited by errors in the waveform transitions between quantized voltages. Many parameters have an impact on the shape of the transients. In this paper, the effect from microwave power and the position of the ground connection on the array chip are discussed.
