摘要：
<正>This paper introduces a mixed continuous-time/discrete-time,single-loop,fourth-order,4-bit audio-band sigma delta ADC that combines the benefits of continuous-time and discrete-time circuits,while mitigating the challenges associated with continuous-time design.Measurement results show that the peak SNR of this ADC reaches 100 dB and the total power consumption is less than 30 mW.
