Fig. 9.21 Current-controlled floating inductance proposed by Sedef et al. [ 18 ]

A negative floating inductor can be realized from the above configuration
(though not so recognized in [ 18 ]) by exchanging the Z+ and Z terminals of

second DO-CCCII as shown in Fig. 9.22 in which case the equivalent floating
inductance is given by:

L ¼ CR x1 R x2 þ ð R x3 Þ ð 9 : 22 Þ

We now present two more circuits proposed by Abuelma atti and Tasadduq [ 20 ],

one of which simulates a floating FDNR and the other one a floating synthetic
