Abstract: The one-port network here includes a pair of terminals and a single differential-input operational amplifier having an output electrically connected through the parallel combination of a resistor R3 and a capacitor C3 to a first input of the amplifier, through a resistor R4 to a second input of the amplifier, and through the series combination of the resistor R3 and a resistor R5 to one terminal of the network which is electrically connected to a ground reference potential. The second input of the amplifier is also connected to ground through a resistor R6. The first and second inputs of the amplifier are electrically connected through an associated capacitor C1 and resistor R2 to the other terminal of the network.

Abstract: The series combination of an FDNR and a resistor is simulated across a pair of terminals of a one-port network which includes a single differential input operational amplifier. One terminal of the network is connected through a first resistor and a second resistor to associated first and second differential inputs of the amplifier. The output of the amplifier is connected through a third resistor to the first input of the amplifier, through the series combination of a first capacitor and a fourth resistor to the second input of the amplifier; and through the series combination of the third resistor and a fifth resistor to the other terminal of the network which is connected to ground. This other terminal is also connected through a second capacitor to the second input of the amplifier.
