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 ...

Mixed-signal map-configurable integrated chaos generator for digital communication systems
(2001)
In this paper, the methodological aspects for the design of mixed-signal map-configurable chaos generators are presented. Such techniques have been applied in the integration, embedded in a complete FM-DCSK modem, of a ...

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 ...
