Reliable analysis of settling errors in SC integrators - application to high-speed low-power ΣΔ modulators design
(1999)
This paper presents a detailed study on the transient response of SC integrators taking into account the effects of amplifier finite gain-bandwidth product and slew-rate during, unlike previous models, both the integration ...

Harmonic Distortion in Fully-Differential Switched-Current Sigma-Delta Modulators
(1999)
This paper presents a systematic analysis of the harmonic distortion in SD modulators (SDMs) implemented with fully-differential switched-current (SI) circuits. Closed form expressions are derived for the third-order ...

Multi-bit cascade ΣΔ modulator for high-speed A/D conversion with reduced sensitivity to DAC errors
(Institute of Electrical and Electronics Engineers, 1998)
This paper presents a ΣΔ modulator (ΣΔM) which combines single-bit and multi-bit quantization in a cascade architecture to obtain high resolution with low oversampling ratio. It is less sensitive to the non-linearity of ...
