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 ...
