1. Differential sampling measurement of a 7 V rms Sine Wave with a Programmable Josephson Voltage Standard
Topic: Quantum Electrical Measurements
Published: 6/1/2013
Authors: Alain Rufenacht, Charles J Burroughs, Paul David Dresselhaus, Samuel Paul Benz
Abstract: A 10 V programmable Josephson voltage standard has enabled sine waves with voltages up to 7 V rms to be accurately measured with a differential sampling measurement technique. Expanding the voltage range for this technique enables direct calibration ...

2. Flat Frequency Response in the Electronic Measurement of the Boltzmann Constant
Topic: Quantum Electrical Measurements
Published: 6/1/2013
Authors: Jifeng Qu, Horst Rogalla, Yang Fu, Jianqiang Zhang, Alessio Pollarolo, Samuel Paul Benz
Abstract: A new quantum voltage calibrated Johnson noise thermometer (JNT) was developed at NIM to demonstrate the electrical approach that determines the Boltzmann constant k by comparing electrical and thermal noise power. A measurement with an integration p ...

3. Johnson Noise Thermometry Measurement of the Boltzmann Constant with a 200 Ohm Sense Resistor
Topic: Quantum Electrical Measurements
Published: 6/1/2013
Authors: Alessio Pollarolo, Tae H. Jeong, Samuel Paul Benz, Horst Rogalla
Abstract: In 2010, NIST measured the Boltzmann constant k with an electronic technique that measured the Johnson noise of a 100 Ω resistor at the triple point of water (TPW) and used a voltage waveform synthesized with a quantized voltage noise source (QV ...

4. Method for Ensuring Accurate AC Waveforms with Programmable Josephson Voltage Standards
Topic: Quantum Electrical Measurements
Published: 6/1/2013
Authors: Charles J Burroughs, Alain Rufenacht, Samuel Paul Benz, Paul David Dresselhaus
Abstract: 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 m ...

5. A 10 V programmable Josephson voltage standard and its applications for voltage metrology
Topic: Quantum Electrical Measurements
Published: 9/3/2012
Authors: Yi-hua Tang, Vijay Ojha, Stephan Schlamminger, Alain Rufenacht, Charles J Burroughs, Paul David Dresselhaus, Samuel Paul Benz
Abstract: The concept of a programmable Josephson voltage standard was first proposed in 1997. Since then a significant amount of research and development work has been devoted to the fabrication of the programmable Josephson junction array and its deployment ...

6. A Digital-to-Analog Converter with a Voltage Standard Reference
Topic: Quantum Electrical Measurements
Published: 7/1/2012
Authors: Alain Rufenacht, Charles J Burroughs, Samuel Paul Benz, Paul David Dresselhaus
Abstract: Commercially available 20-bit digital to analog converters (DACs) have the potential to impact the field of low frequency voltage metrology. We measured a linearity of ±6 µV (±0.6 µV/V full scale) over the 10 V range for such a DAC with a Zener volta ...

Topic: Quantum Electrical Measurements
Published: 7/1/2012
Authors: Alessio Pollarolo, Tae H. Jeong, Samuel Paul Benz, Horst Rogalla
Abstract: In 2010 NIST measured the Boltzmann constant k by use of an electronic technique that measured the Johnson noise of a 100 Ohm resistor at the triple point of water (TPW). The NIST Johnson noise thermometry (JNT) system used as a reference a voltage ...
