Summary The objective of this proposal is to design and simulate a novel high-resolution RF SQUID ADC that uses only three single-JJ SQUID to significantly extend the flux detection range. A unique resonant detection method based on the robust symmetrical number system (RSNS) will be used to provide a high resolution representation of the input magnetic flux. The architecture to be investigated breaks down the flux detection operation into N = 3 parallel sub-operations (moduli) that are of smaller computational complexity. Consequently, each sub-operation only requires a precision in accordance with that modulus and a much higher RF voltage resolution is achieved after the N different moduli are used and the results of these low precision sub-operations are recombined. In addition, the dynamic range of the RF SQUID ADC is greatly extended.
