Hi, all,
I am studying SC Sigma Delta ADC, and have questions on an integrator part.
The switched capacitor integrator consists of OP-amp, switches and capacitors, and I wonder how the capacitors affect the performance of integrators or Sigma Delta Modulator.
To my knowledge, the transfer function of the integrator does not depend on their values of two capacitors but depends on the ratio of two capacitors.
Then, what other effects do these capacitors have on sigma delta ADC?
As long as the ratio of two capacitors are fine, does the sigma delta work fine?
Thank you in advance,
