Abstract: The present paper discusses the development of a specific type of selective LC amplifier with an active inductor and a current-feedback amplifier (CFA) with an additional port for control. The active inductor (gyrator) is built on the base of a general impedance converter (GIC), consisting of two op amps and RC-elements. The gyrator transforms the capacitance of the circuit to the emulated inductance. The main advantages of this new configuration are the insignificant influence of the load over the parameters of the amplifier and the possibility for independent tuning of the voltage gai
