| Abstract: | A design method for full-integrated OTA filter based on double terminated LC ladder is presented. The filter is composed of OTA and ground capacitors. This architecture is beneficial to circuit integration and elimination of effects of parasitic capacitors. A design example is given. Simulation results show that the proposed method is applicable to continuous time full-integrated OTA filter design. |
