Abstract :
In this paper a second order multi-mode allpass filter is proposed. The main feature of this configuration is that, it can be used in current mode (CM), voltage mode (VM), transimpedance mode (TIM) and transadmittance mode (TAM) without changing the configuration. This filter uses a single current differencing buffered amplifier (CDBA) and a total of five/six passive components. The validity of the proposed filter is verified through PSPICE simulations and results are in good agreement with theoretical one.
