Operating Conditions for a Pulse-Quantized AC and DC Bipolar Voltage Source

June 1, 1999
Author(s)
Samuel Benz, Charles J. Burroughs, Todd E. Harvey, Clark A. Hamilton
We have developed an accurate ac and dc bipolar voltage source based on the quantized pulses of Josephson junctions. A factor-of-6 increase in output voltage over previous unipolar waveforms is achieved by generating bipolar waveforms where arrays of

Operating Margins for a Superconducting Voltage Waveform Synthesizer

June 1, 1999
Author(s)
Samuel Benz, Clark A. Hamilton, Charles J. Burroughs
Operating margins for biolar superconducting voltage waveform synthesizer were measured. Current ranges were determined for 101 equally spaced dc voltage steps between - 18.6 and + 18.6 mV. The measured voltages of these steps deviated from the expected

Programmable 1 V DC Voltage Standard

April 1, 1999
Author(s)
Charles J. Burroughs, Samuel Benz, Clark A. Hamilton, Todd E. Harvey
We have developed a Josephson voltage standard that produces intrinsically stable voltages that are programmable of 32 768 SNS (superconductor-normal-superconductor) Josephson junctions. The output can source or sink up to 2 mA and thus has high noise

Pulse-Driven Josephson Digital/Analog Converter

June 1, 1998
Author(s)
Samuel Benz, Clark A. Hamilton, Charles J. Burroughs, Todd E. Harvey, Laurie Christian, J. X. Przybysz
We have designed and demonstrated a pulse-driven Josephson digital/analog converter. When used as a programmable voltage standard, this device can synthesize metrologically accurate ac waveforms as well as stable dc voltages. We show through simulations
