| Abstract: | A novel single-amplifier switched-capacitor (SC) fiter is presented. Design of the least capacitor spread for it is given. The effects of passive sensitivities and limited GB on the new circuit are investigated. Analysis and design show that the proposed circuit have much less capacitor spread, total capacitance, and lower limited GB effects. The validity for. it is verified by the experment with discrete elements. |
