11. He became interested in tuners such as a gyrator and a phase-locked loop ( PLL ). 12. Real inductors are increasingly being replaced by active circuits such as the gyrator which can synthesize inductance using capacitors. 13. By analogy, a transducer that converts non-analogous variables between energy domains is also called a gyrator . 14. The gyrator , on the other hand, maps a voltage at one port to a current at the other. 15. Gyrator inductors typically have higher accuracy than physical inductors, due to the lower cost of precision capacitors than inductors.16. The gyrator is a necessary element in analysis because it is not practical gyrator must be constructed as an active circuit. 17. The gyrator is a necessary element in analysis because it is not practical gyrator must be constructed as an active circuit. 18. Since gyrators use active circuits, they only function as a gyrator within the power supply range of the active element. 19. At low frequencies and low powers, the behaviour of the gyrator can be reproduced by a small op-amp circuit. 20. In typical applications, both the inductance and the resistance of the gyrator are much greater than that of a physical inductor.
