Josephson-Based Full Digital Bridge for High-Accuracy Impedance Comparisons

Author(s)
Frederic Overney, Nathan E. Flowers-Jacobs, Blaise Jeanneret, Alain Rufenacht, Anna E. Fox, Jason M. Underwood, Andrew D. Koffman, Samuel P. Benz
This paper describes a Josephson-based impedance bridge capable of comparing any types of impedance over a large bandwidth. The heart of the bridge is a dual AC
