ABSTRACT:
There is provided a superconducting multi-stage sigma-delta modulator including a first superconducting sigma-delta modulator having a first integrator and a first comparator and outputting a sigma-delta modulated signal and a second superconducting sigma-delta modulator having a second integrator and a second comparator and outputting a sigma-delta modulated signal. The first integrator and the second integrator are magnetically coupled.
