Abstract
A superconducting bandpass sigma-delta Analog-to-Digital Converter (ADC) is disclosed. The ADC is characterized as being an N-order, having N resonators, with N being at least 2. The ADC also may have N−1 amplifiers, where the amplifiers directionally couple sequential pairs of the resonators. The ADC further includes a Josephson Junction (JJ) comparator. All N resonators connect in parallel to the JJ comparator, and the JJ comparator is providing an implicit feedback for all N resonators. A method for implementing the sigma-delta ADC without any explicit feedback loops is also disclosed.
