本文介绍了一种使用约瑟夫森波形合成器和跨导放大器来校准交流-直流电压传递差的热转换器的简单而有效的技术。初步测量和不确定度分析证实,在频率高达1 kHz时,系统不确定度可能低于0.1uV V−1。
This paper describes a simple and effective technique for calibrating thermal converters for an ac–dc voltage transfer difference using a Josephson waveform synthesizer and a transconductance amplifier. Preliminary measurements and uncertainty analysis confirm the possibility of achieving systematic uncertainties below 0.1 µV V−1 at frequencies up to 1 kHz.
