Beschreibung
Zusammenfassung:	According to one embodiment, a sensor circuit comprises a sigma-delta analog-to-digital converter (ADC), a dithered clock which is coupled to the sigma-delta ADC, and a power supply circuit which is coupled to the sigma-delta ADC. The sigma-delta ADC is configured to be coupled to a low-frequency transducer and the dithered clock is configured to control the sigma-delta ADC based on a dithered clock signal. 根据个实施例，种传感器电路包括Σ-Δ型模数转换器(ADC)、耦合至Σ-Δ型ADC的抖动时钟以及耦合至Σ-Δ型ADC的电源电压电路。Σ-Δ型ADC被配置为耦合至低频换能器，并且抖动时钟被配置为基于抖动时钟信号控制Σ-Δ型ADC。
