Abstract :
The most popular design method for switched capacitor (SC) filters is using SC integrators. however, highpass and band-elimination filters cannot be directly obtained, because the original switched filter graphs have to be modified. The authors present a straightforward design technique for SC band-elimination ladder filters using the extended biquad, which gives the sum function of integration and differentiation
