A CMOS fully-differential bandpass ΣΔ modulator using switched-current circuits
(Institute of Electrical and Electronics Engineers, 1995)
This paper presents a fourth-order bandpass sigma-delta modulator that has been designed using fully-differential switched-current circuits in a 0.8μm CMOS technology. The modulator prototype has been obtained by applying ...

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 ...

Nonlinear switched-current CMOS IC for random signal generation
(Institution of Engineering and Technology, 1993)
A nonlinear switched-current circuit is presented that implements a chaotic algorithm for the generation of broadband, white analogue noise. The circuit has been fabricated in a double-metal, single-poly 1.6µm CMOS technology ...

Non-ideal quantization noise shaping in switched-current bandpass ΣΔ modulators
(Institute of Electrical and Electronics Engineers, 1999)
This paper presents a systematic analysis of the major switched-current (SI) errors and their influence on the quantization noise shaping of SI BandPass SD Modulators (BPSDMs). Closed form equations are provided for the ...

Analysis of error mechanisms in switched-current Sigma-Delta modulators
(Springer, 2004)
This paper presents a systematic analysis of the major switched-current (SI) errors and their influence on the performance degradation of ΣΔ Modulators (ΣΔMs). The study is presented in a hierarchical systematic way. First, ...
