In a discrete-time delta-sigma ADC, sampling of the input signal x ... performance of a continuous-time ADC. There are key differences between a discrete-time DAC using switched-capacitor circuits ...

Oversampling helps to reduce quantization noise, which is the sampling ... Any analog signal between these two values is rounded off to either zero or one, and the resulting difference is the ...
