Zero-Compensation Josephson Arbitrary Waveform Synthesizer at 1.33 V

摘要

This paper describes the generation of a quantum-based rms output voltage of 1.332 V using an ac-coupled Josephson Arbitrary Waveform Synthesizer (JAWS) without any low-frequency compensation current biases, that is, in a `zero-compensation' (ZC) mode. Low-frequency bias currents result in unwanted error voltages that increase with frequency. The ZC technique minimizes these currents and removes the resultant error voltages.
