This paper recounts the development of a superconducting bandpass delta-sigma Γ°DRΓ modulator for direct analogto-digital conversion of radio frequency signals in the GHz range. The modulator design benefits from several advantages of superconducting electronics: high-Q resonators, fast Josephson com
We studied the signal-to-noise ratios (SNRs) of a superconducting first-order sigma-delta modulator with an LR integrator. Effects of leakage in the LR integrator and thermal noise on SNR were investigated analyzing a transfer function and simulating circuits with thermal noise sources. Leakage resu
