摘要

本文提出了一种用于音频应用的连续时间变焦ADC。与以前的变焦adc相比，它的输入阻抗主要是电阻性的，使得它更容易驱动，同时仍然保持高能效。该原型机采用0.16 ×m CMOS工艺制作，占地0.27 m m2，在20 kHz BW下实现108.5 dB DR、108.1 dB SNR和106.4 dB SNDR，功耗为618 ×W。这就产生了最先进的183.6 dB的Schreier FoM。

A Low Power Continuous-Time Zoom ADC for Audio Applications

This paper presents a continuous-time (CT) zoom ADC for use in audio applications. Compared to previous zoom ADCs, its input impedance is mainly resistive, making it much easier to drive while still maintaining high energy efficiency. The prototype is fabricated in a 0.16 ×m CMOS process, occupies 0.27 m m2 and achieves 108.5 dB DR, 108.1 dB SNR, 106.4 dB SNDR in a 20 kHz BW, while consuming 618 ×W. This results in a state-of-the-art Schreier FoM of 183.6 dB.
