摘要

本文提出了一种基于VHDL-AMS语言的连续时间(CT)正交带通(QBP) ΔΣ调制器的行为建模、仿真和设计方法。在此基础上，建立了一套考虑非理想效应的行为模型。许多五阶CT QBP的行为模拟ΔΣM说明并量化了这些非理想效应的影响。

VHDL-AMS modeling of non-idealites effects in Continuous-time quadrature bandpass ΔΣ modulator

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.
