| Abstract: | A new second-order universal active current-mode filter based on OTA-C was presented. The filters have one output and three inputs. Each kind of filter such as low-pass, high-pass, band-pass, notch and all-pass filter can be obtained by selecting the corresponding input signal combinations. The proposed citcuit is with simple structure, separately adjustable centre frequency and the quality factor, low passive sensitivities (equal 0.5). Theoretical analysis and SPICE simulation indicate that the proposed circuit is effective and feasible. |
