论文摘要
在本文中,通过考虑带通路类似物到数字的转换,证明了控制束缚的类似物到数字转换器原理的设计灵活性。我们展示了如何将低通控制的模数转换器转换为带通的版本,在该版本中,可以保留保证的稳定性,转换器带宽和信噪比,而可以自由定位转换中心频率。提出的转换器通过行为模拟验证了各种过滤器订单,缺口滤波器频率和过采样比率。最后,蒙特卡洛模拟证明了针对组件变化的鲁棒性。
In this paper, the design flexibility of the control-bounded analog-to-digital converter principle is demonstrated by considering band-pass analog-to-digital conversion. We show how a low-pass control-bounded analog-to-digital converter can be translated into a band-pass version where the guaranteed stability, converter bandwidth, and signal-to-noise ratio are preserved while the center frequency for conversion can be positioned freely. The proposed converter is validated with behavioral simulations for a variety of filter orders, notch-filter frequencies, and oversampling ratios. Finally, robustness against component variations is demonstrated by Monte Carlo simulations.
