A fourth-order bandpass ΣΔ modulator using current-mode analog/digital circuits
(Institute of Electrical and Electronics Engineers, 1996)
We present a fourth-order bandpass ΣΔ switched-current modulator IC in 0.8 μm CMOS single-poly technology. Its architecture is obtained by applying a lowpass to bandpass transformation (z-1 →-z-2) to a second-order lowpass ...

Experimental Characterization of IdleTones in Second-Order Bandpass ΣΔ Modulators
(2000)
This paper analyses the tonal behaviour of the quantization noise in second-order bandpass ΣΔ modulators. The analysis performed for lowpass modulators is extended to the bandpass case. As a result, closed form expressions ...
