摘要:
This specification describes networks having gyrator properties. Each network comprises two differential amplifiers, and four resistors (conveniently equal) connected in positive and negative feedback paths about the amplifiers. The feedback connections are such that the networks are unconditionally stable. When a network is capacitively terminated it input port impedance is inductive. If in each of a group of capacitively terminated networks one of the feedback resistors is replaced by one of a group of input ports of a network of resistors the input ports of the gyrator networks simulate corresponding input ports of a network of inductors topologically and proportionally the same as the resistor network.
