| Abstract(in English) | We are developing a new implementation of quantum voltage noise source (QVNS), integrated QVNS (IQVNS), for Johnson noise thermometry (JNT), aimed at thermal metrology applications. By using a Fourier analysis method, we have derived a generalized expression for power spectrum densities (PSDs) of IQVNS. The PSD expression has shown that the frequency dependence of PSD becomes weaker as the IQVNS circuit operates faster. Some improvements have been suggested for better properties of the IQVNS PSD used in precise JNT measurements. Characteristics and calculation precision of the IQVNS PSD are discussed quantitatively. |
