Notes
This is a sensing device which is attached to a node in the circuit and produces as an output, a scaled value equal to the total inductance seen on its input, multiplied by the value assigned to the Gain parameter. This model is useful as a building block for other models, which require to sense an inductance value and adjust their behavior with respect to it.
The input signal can be either a single-ended current or single-ended voltage signal.
Examples
Consider the inductance meter in the above image, with the following characteristics:
Pin1 (input) is connected to net NetL1_2
Pin2 (output) is connected to net Out
Designator is U1
Gain = 10
The entry in the SPICE netlist would be:
*Schematic Netlist:
AU1 NetL1_2 OUT AU1LMETER
.MODEL AU1LMETER lmeter (gain=10)
The effect of the function can be seen in the resultant waveforms obtained by running a transient analysis of the circuit:
