Comment on "A new approach for lossless floating inductor simulation

It is pointed out that the approach adopted for simulating a lossless floating inductor by Patranabis et al. in the above \footnote[1]{paper} is not new. In fact, their configuration, proposed in an arbitrary manner, has already been systematically derived [3]. An alternative systematic approach is proposed here. (1)D. Patranabis, M. P.
