A universal current-mode active-only filter is proposed. The proposed circuit is realized byminimized active-only components (four current-controlled second generation current conveyors and twoOperational Amplifiers ) without external passive elements, which can simultaneously realize five standardfilter functions as lowpass(LP), highpass(HP), bandpass(BP), band-stop(BS) and all-pass(AP) responsefrom the same configuration. The parametersωp can be electronically tuned through adjusting theparasitic resistance of the CCCII and the frequency response can be linearly tuned through thetransconductance gain of TCCIIs . Moreover, the parameter sensitivities are all very low. Pspicesimulation results are given to verify the circuit performance.
