Superconducting delta-sigma oversampling A/D converter

Abstract

A superconducting delta-sigma analog-to-digital (A/D) converter is presented. The converter uses a low-pass filter instead of the integrator found in the usual delta-sigma architecture. The converter is analyzed by a behavior-level simulation package as well as the circuit simulator JSIM. Its performance is compared to that of the standard first-order delta… (More)
