CT ∆ΣADCs advantage:
1) high speed and low power requirement
2) inherent anti-aliasing properties without SC noise
3) lower the switch performance without the SC based front-end
4) high input impedance and save the input buffer
5) absence of stringent settling requirements enables CT converters to digitize signals up to several hundred MHz
disadvatages:
1)sensitive to clock jitter 2)the loop coefficient are sensitive to technology parameters
3)modulator is dependent on clock frequency 4)sensitive to feedback loop delay
SC ∆ΣADCs advantage:
1)mature design methodologies and robustness2)achieve relatively high linearity and high resolution
3) tolerant of clock jitter4) the filter coefficients are very stable 5)the filter coefficients is independent on clock frequency
