摘　　要：在混合滤波器组ADC系统广泛用于通信领域的背景下,提出一种基于带通电荷取样滤波器的混合滤波器组模型。采用两种方法对模型进行建模,分析模型对采样时序误差的敏感度。通过两种方法得出的一致结果表明:该模型对时序误差敏感度低,验证了其可靠性。Under the background that Hybrid filters bank ADC is widely used in the field of communication today. A hybrid filter bank model based on the bandpass charge sampling filter was proposed. The modeling of this model was achieved in two methods and the sensitivity of the model to the jitters was studied. The consistency of this two methods shows the low sensitivity to jitters and verifies the reliability of this model.
