In Continuous Time Delta Sigma ADC, there are two options in Feedback DAC generally.
(1) Current DAC
(2) Voltage DAC or Resistive DAC
Regarding thermal and flicker noise, (2) have advantage.
Regarding calibration for multi level DAC, (1) have advantage.
Regarding speed, (1) have advantage.
(1) occupy large area than (2) generally.
Regarding glitches, (1) is severe.
Totally for less level and not high speed DAC, I think (2) is good especially for regrading noise and glitches.
How do you think ?
