Leakage Current Effects with Programmable Josephson Voltage Standards

Author(s)
Alain Rufenacht, Charles J. Burroughs, Stephane S Solve, Anna E Fox, Raegan L Johnson-Wilke, Benjamin T Scheck, Paul D Dresselhaus, Samuel P Benz
This work presents the results of evaluating and measuring the dc leakage effects associated with Programmable Josephson Voltage Standards (PJVS). Two types of leakage error can occur in PJVS systems

Josephson Voltage Standard

NIST Inventors
Samuel P. Benz , Paul Dresselhaus , Alain Rufenacht and Anna Fox
It was determined that a device having simultaneous voltage reference signals would be useful for many measurement and calibration activities. A JVS advantageously having multiple output leads would meet this criterion, and provide such voltage references without the need for multiple systems
