Description

An ideal gyrator: the current at each port is set by the voltage at the other. It turns a capacitor on one side into an inductance on the other, and conserves power when G1 = G2.

Example

Controlled sources Voltage- and current-controlled sources and a gyrator, each driving a 10 Ω load.

Equations

v1 = p1.v − n1.v, i1 = p1.i, p1.i + n1.i = 0
v2 = p2.v − n2.v, i2 = p2.i, p2.i + n2.i = 0
i1 = G2 · v2
i2 = −G1 · v1

Tips

  • A capacitor C on port 2 appears at port 1 as an inductance C / (G1 · G2).
