Hi ,all
Is the "overload level factor" important in sigma delta?
I ready a peper(Mohammad Yavari,Omid Shoaei, A very low-voltage,low-power and high-resolution sigma-delta modulator for digital audio in 0.25-um CMOS) that present the gain should be low in passband!!!it can improve "overload level factor"!!
But the high gain of OPA is better than low gain,isn't it??
thanks!!
