| Abstract: | A novel current-mode (CM) first-order all-pass (AP) inverse filter has been presented. The proposed circuit has two inputs and a single output with both the inputs providing the first-order all-pass inverse responses independently. The circuit employs bare minimum number of both active and passive components, viz. one each of CDTA, capacitor and resistor. The output current is available at high impedance thereby making the circuit very attractive from the viewpoint of cascadibility. The realizibility condition is simple. The theoretical results are verified by PSPICE simulation. |
