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 series combination of a resistor R3 and capacitor C3 to a first input of the amplifier, through a resistor R4 to the second input of the amplifier, and through a resistor R7 to one terminal of the network. The first and second inputs to the amplifier are also electrically connected through an associated resistor R1 and capacitor C2 to the one network terminal. The other network terminal is connected to a ground reference potential and through resistors R5 and R6 to the first and second inputs, respectively, of the amplifier. With normalized values of network elements satisfying prescribed criteria, the impedance presented across the network terminals corresponds to that of the series combination of a super-inductor, an inductor, and a resistor. By proper selection of element values, the impedance simulated across the network port may be adjusted to correspond to that of a resistor alone or in series with an inductor, or these two elements individually in series with a super-inductor.
