how does switched capacitor filter work
i am very new in switched capacitors stuff,i know that SC filters are nowadays very popular,and also know that f and c can generate the resistance,but how did the switched cap generate the cut off frequency of filters?as far as i know,all the poles need R and C,where is the C come from in the switched caps?
