...The converter is operated with much higher frequency than the Nyquist-frequency of the input signal, which is called oversampling [12]....
[...]
...The other useful feature is the guaranteed linearity [12], which is caused by the 1-bit DAC and the averaging method....
[...]
...There are many existing improvements of the Σ − ∆ DAC: higherorder and MASH-modulators [12] or sliding-mode control...

...Using more bits naturally increases SNR and makes lower oversampling ratio possible but also reduces linearity [12]....
