Realization of OTA-C current-mode universal filter based on two type integrators loop

A universal current-mode active filter based on 2 types of integrator, lossy and lossless integrators, is presented. The biquadratic transfer function is obtained by the two integrators loop. The proposed circuit employs only 2 multiple output OTAs (MO-OTA) and 3 capacitors. The parameter Qp can be wide-range tuned independent from the omegap either… (More)
