Abstract

Abstract

Sigma-Delta (Σ-Δ) Analog-to-Digital Converter (ADC) is based on oversampling and noise shaping techniques to achieve high-resolution, and is characterized by low passive component matching requirements and simple structure. In high-resolution audio applications, Σ-Δ ADC has gained widespread attention and applications since it can achieve high dynamic range with good power efficiency. Recently, there has been a growing research trend in designing low-power, high-resolution audio ADCs using advanced processes and technologies. However, with process technology going to lower nodes and the reduction of supply voltages, the circuit design becomes more challenging. This paper reviews the state-of-the-art of the discrete-time and continuous-time design of high-resolution audio Sigma-Delta modulators, provides theoretical background for the design of high-resolution audio Sigma-Delta modulators, and gives research prospects.
