该论文提出了一种动态Zoom-ADC，通过将SAR ADC与ΔΣ ADC动态结合，解决了传统Zoom-ADC只能处理准静态信号的问题，使其能处理时变信号。在20kHz带宽内实现了107.5dB动态范围，仅消耗1.65mW功率和0.16mm2面积，兼具高能效和小尺寸。
stereo channels to achieve effective acoustic noise and echo cancellation, thus demanding ADCs with low power and minimal die area. Zoom-ADCs should be well suited for such applications, since they combine compact and energy-efficient SAR ADCs with low-distortion ΔΣ ADCs to simultaneously achieve high energy efficiency, small die area, and high linearity [1,2]. However, previous implementations were limited to the conversion of quasi-static signals, since the two ADCs were operated sequentially, with a coarse SAR conversion followed by, a much slower, fine ΔΣ conversion. This work describes a zoom-ADC with a 20kHz bandwidth, which achieves 107.5dB DR and 104.4dB SNR while dissipating 1.65mW and occupying 0.16mm2. A comparison with recent state-of-the-art ADCs
