Abstract :
This paper presents an approach of behavioral modeling, simulation, and design of Continuous-time (CT) quadrature bandpass (QBP) ΔΣ modulator using VHDL-AMS language. A set of specific behavioral models taking into account non-idealities effects such excess loop delay and jitter are developed. Numerous behavioral simulation of a fifth-order CT QBP ΔΣM illustrates and quantifies the impact of these non-idealities effects.
