Abstract
Proposed stability test for RLC low-pass filters is presented. The self-loop functions of these filters are derived and analyzed based on the widened superposition principle. The alternating current conservation technique is proposed to measure the self-loop function. An active inductor is replaced with a general impedance converter. Our research results show that the values of the selected passive components (resistors, capacitors, and inductors) in these filters can cause a damped oscillation noise when the stable conditions for the transfer functions of these networks are not satisfied.
