Systematic errors in the correlation method for Johnson noise thermometry: residual correlations due to amplifiers
Luca Callegaro, Marco Pisani, Massimo Ortolano
Johnson noise thermometers (JNT) measure the equilibrium electrical noise, proportional to thermodynamic temperature, of a sensing resistor. In the correlation method, the same res…
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…
