Gyrator
The perfect gyrator.
Description
The Gyrator can be used to realise inductance using a capacitor. The main advantage of the gyrator is that an equivalent inductance can be created using a capacitor much smaller than a coil. In practice, the gyrator is realised using an operational amplifier and additional passive elements.
The Gyrator block represents an ideal lossless gyrator described by the following equations:
Where:
-
- input voltage;
-
- output voltage;
-
- current flowing into the input positive terminal;
-
- current flowing out of the output positive terminal;
-
- equivalent conductivity of the gyrator.
Each of the two circuits connected to the primary and secondary windings must have its own Electrical Reference block.
Ports
The block has four electrical ports. Polarity is indicated by + and - . Ports labelled 1+ and 1- represent the primary winding terminals. Ports labelled 2+ and 2- represent the secondary winding terminals.
