| 摘 要： | 提出利用单通路滤波来有效抑制引入模拟器件偏差后混合滤波器组(Hybrid Filter Banks)ADC系统性能的恶化.从理论上证明单通路滤波结构对模拟偏差有很好的抑制作用,并通过仿真验证了这一理论.在模拟器件偏差为1%,5%,10%的情况下,单通路滤波HFB ADC系统与传统两通路滤波系统相比较,可将信噪比提升分别为42 dB,44 dB和45 dB.

| Abstract: | The dramatic performance degradation of Hybrid Filter Banks(HFB) ADC could be seen in the presence of analog realization errors.Thus,a single-channel filtering architecture to restrain analog device error of HFB is presented.The validity of this architecture is proved by theories as well as simulations.Comparing with traditional HFB ADC structure,the signal-to-noise ratio(SNR) of the single-channel filtering structure can be enhanced about 42 dB,44 dB,45 dB according to 1%,5%,and 10% analog device errors ca... |
