Automated DC Voltage and DC Resistance Real-time Multiple Standard for Artifact Calibration of Calibrators and multimeters
F. Gallianaa, P. Capra, R. Cerri +4
An automated temperature-controlled electrical DC voltage and DC resistance multiple reference standard (MRS) has been developed by Measurements International (MI) with the scienti…
Improved electronic measurement of the Boltzmann constant by Johnson noise Thermometry
Jifeng Qu, Samuel P Benz, Alessio Pollarolo +4
The unit of thermodynamic temperature, the kelvin, will be redefined in 2018 by fixing the value of the Boltzmann constant, k. The present CODATA recommended value of k is determin…
An absolute Johnson noise thermometer
Luca Callegaro, Vincenzo D'Elia, Marco Pisani +1
We developed an absolute Johnson noise thermometer (JNT), an instrument to measure the thermodynamic temperature of a sensing resistor, with traceability to voltage, resistance and…
Very simple FET amplifier with a voltage noise floor less than 1 nV/sqrt(Hz)
Luca Callegaro, Marco Pisani, Alessio Pollarolo
A field-effect transistor (FET) amplifier for small voltage signals is presented. Its design is elementary and the construction can be afforded by anyone. Despite its simplicity, w…
