我们使用集成量子电压噪声源（IQVNS）进行约翰逊噪声测温（JNT），该噪声源产生伪随机噪声，其RMS值由通量量子、IQVNS时钟频率、fclk和可计算系数的乘积决定。其工作原理与传统的QVNS不同。对IQVNS的波形进行了彻底的分析，并对源进行了检查，以确保它按预期正常工作，特别是考虑到它作为JNT测量参考的适用性。用IQVNS测量了电阻器在水三相点处的热噪声功率，得出了玻尔兹曼常数的值。
We performed Johnson noise thermometry (JNT) using an integrated quantum voltage noise source (IQVNS) that generates pseudorandom noise with an RMS value determined by the product of the flux quantum, the clock frequency of IQVNS, fclk, and a calculable coefficient. The working principle is different from the conventional QVNS. The waveform of the IQVNS was analyzed thoroughly, and the source checked to see that it worked properly as intended, particularly in regard to its applicability as a reference for JNT measurements. The thermal noise power of a resistor at the triple point of water was measured with the IQVNS to derive a value of the Boltzmann constant.
