A 13-bit, 2.2-MS/s, 55-mW multibit cascade ΣΔ modulator in CMOS 0.7-μm single-poly technology
(Institute of Electrical and Electronics Engineers, 1999)
This paper presents a CMOS 0.7-μm ΣΔ modulator IC that achieves 13-bit dynamic range at 2.2 MS/s with an oversampling ratio of 16. It uses fully differential switched-capacitor circuits with a clock frequency of 35.2 MHz, ...

A CMOS 0.8 μm fully differential current mode buffer for HF SI circuits
(Elsevier, 1998)
We present a high-frequency fully-differential current-mode buffer to interface off-chip currents with no significant degradation of the frequency response, and to measure current-mode ICs using standard equipment. It has ...

Fourth-order cascade SC ΣΔ modulators: a comparative study
(Institute of Electrical and Electronics Engineers, 1998)
Fourth-order cascade ΣΔ modulators are very well suited for IC implementation using analog sampled-data circuits because of their robust, stable operation and their capability to achieve high resolution and wide bandwidth ...

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, ...
