Three port gyrator circuits using transconductance amplifiers or generalized conveyors

The three port gyrator was introduced and defined in [1] in two alternative forms of the admittance matrix (Y). Four alternative realizations of the three port gyrator using three transconductance amplifiers (TA) are given, three of them are new. Sixteen alternative three port gyrator circuits using four current conveyors (CCII) or four inverting current conveyors (ICCII) or a combination of both of them and four grounded resistors are given. Eight alternative three port gyrator circuits using two CCII or two ICCII or a combination of both of them, balanced output current conveyors (BOCCII) and three grounded resistors are also introduced. Eight alternative three port gyrator circuits using two CCII or two ICCII or a combination of both of them, differential voltage current conveyors (DVCC) and three grounded resistors are also introduced. Finally four equivalent three port gyrator circuits using a combination of DVCC and BOCCII and two grounded resistors are also introduced, three of them are new.
