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 ...
