From the above matrix, it can easily be seen that even non-ideally; all the
y-parameters of the circuit still represent lossless inductance i.e. the basic nature
of the Y parameters of the FI remains unchanged even non-ideally. Furthermore,
from the non-ideal matrix above, it can be easily confirmed that the circuit
also enjoys very low active and passive sensitivities all of which are confined to
the range
