On the Four Terminal Floating Nullor (FTFN) and the Operational Mirror Amplifier (OMA)
Ahmed M Soliman
Several realizations for the CCII- and CCII+ are reviewed. It is pointed out that introducing a polarity for the norator to model the CCII+ is not correct. It is also pointed out that introducing a polarity for the Four Terminal Floating Nullor (FTFN) in order to serve a purpose in circuit realization is also not correct. It is emphasized that both Norator as well as the FTFN have no polarity and the pathological current mirror and the Operational Mirror Amplifier (OMA) serves to correct this ambiguity.
Keywords: Operational mirror amplifier; nullor; CCII+; pathological current mirror.
