Circuit Description
Circuit Graph
The circuit is an ideal gyrator, back-to-back voltage-controlled current sources (VCIS) with port 2 terminated by a capacitor to simulate an inductor.
L = C / (Gm1 · Gm2)
L = 1 µF / (0.1 S · 0.1 S)
L = 1 µF / (0.01 S²)
L = 100 µH
where Gm1 and Gm2 are the transconductances of the VCISs.
With a triangular current feed at port 1, the voltage developed is a square wave. The voltage is proportional to the rate of change of the input current and scaled by the simulated inductance.
Vin = L (dIn / dt)
Vin = [C / (Gm1 · Gm2)] (dIn / dt)
