Abstract
Two active configurations for simulating tunable floating and grounded lossy inductors are described. Each simulated inductor circuit contains only a single fully balanced-voltage differencing buffered amplifier (FB-VDBA), one resistor, and one capacitor. The equivalent values of the simulated elements can be tuned independently through the FB-VDBA’s bias current and/or the resistor in the circuit. Non-ideal analysis of the synthetic inductors is also provided. The practical use of the proposed FB-VDBA based lossy inductance simulators is demonstrated on both a second-order RLC low-pass filter and a parallel RLC resonance circuit. PSPICE simulation results are provided to evaluate the presented theory.
