Biquad Fiters with RC Feed Back&its Effect Over The Stability on the Poles of the Amplifiers: A New Dimensional Study

Wide variety of networks and active filters has acknowledged concentration in active resistor-capacitor networks (RC networks). Few of limitations in the linear filters, a unique combination of resistor (R), Inductor (I) and capacitors (C) and are not dependent on any external supply or in other words passive filters is entirely removed in active filters those are composed of active component such as an external amplifier to adjust the required gain. The current investigation to reduce the circuit by means of enhances the package density and the trustworthiness of the circuit as an important objective in the present study. It was almost impossible not to integrate the inductor with the experimental readings of inductance and reasonable Q factors. As RC filters can be realized with a Q value 0.5 and with this value its almost impossible to fabricate a lofty selectivity filter.
