Al-Janabi, M., Kale, I. and Morling, R.C.S. (1999) Narrow-band variable center frequency single-loop and multistage sigma-delta modulators for bandpass signals. IEEE Transactions on Instrumentation and Measurement, 48 (5). pp. 873-877. ISSN 0018-9456Full text not available from this repository.
Oversampled narrow-band single-loop and multistage resonator-based bandpass sigma-delta (Σ-Δ) modulators that can accommodate different passband center to sampling frequency ratios are reported. These tunable bandpass configurations are designed by analytically determining and subsequently verifying through detailed empirical simulations the required compensation hardware to deliver enhanced noise-shaping. It is demonstrated that comparatively superior in-band signal-to-noise ratios and dynamic ranges are attributed to the inclusion of appropriate digital feedforward and feedback compensators within these structures.
