摘要: A novel single-input second-order multifunction filter realized by employing current mirrors is introduced in this manuscript. The proposed topology offers simultaneously the lowpass, highpass, bandpass, and bandstop frequency responses. Other attractive characteristics are its potential for low-voltage operation electronic tuning. In addition, only passive elements used realizing filters grounded capacitors. could become universal additional circuitry. Simulation results confirm correct of structure.
