According to NAM expansion method and adjoint network theorem, the systematic synthesis method of CCCCTA-based current-mode Wien oscillators is given and three different classes of the oscillators are derived. The class I oscillators have 16 different forms, the class II oscillators have 24 different forms, and the class III oscillators have 16 different forms. Since the circuits use fewer active elements and grounded capacitors, the circuits are easy to be integrated and provide the attractive feature of independent electronic control of the condition and frequency of oscillation. The circuit analysis and computer simulation results have been included to support the generation method.

“…It can be readily seen that this expanded matrix contains two different pairs of pathological elements, one floating admittances, and three grounded admittances. After adding the two capacitors C 1 and C 2 at nodes 1 and 2, respectively, the nullor-mirror equivalent model described by (8) is shown in Fig. 2.…”

“…When the proposed theory is applied to the circuit of Fig. 9, the number of equivalent circuits having the same CE [It may be pointed out that alternative methods of analysing OTA‐RC oscillators to find their CE using nullator–norator representations have been described in [41–44]. ] as (2) have been found to be ten (however, to conserve space, these have not been shown here).…”

“…Lately, a large number of research articles have reported the nodal admittance matrix (NAM) expansion method [1–33], which can be used to synthesise linear active circuits like gyrators, oscillators, and filters. According to this method, the literature [32] presents two different topologies of the gyrators, namely the types I and II gyrators.…”

A systematic synthesis approach for floating gyrators employing single z-copy current-controlled current conveyor trans-conductance amplifier (CCCCTA) is presented in this work. Initially, the pathological models of two types of the CCCCTA, namely z-copy z +-output CCCCTA (CCCCTA+) and z-copy z −-output CCCCTA (z-copy CCCCTA−), are derived by virtue of the nodal admittance matrix (NAM) expansion method. Moreover, these models are then used in the synthesis of floating gyrator using single z-copy CCCCTA. Two floating gyrators are acquired by expanding the NAM of floating gyrator. The synthesised gyrators employ one z-copy CCCCTA and a grounded admittance. Adjusting bias currents of the CCCCTA can tune the parameter of the gyrators. The hand analysis and PSPICE simulation show that the used synthesis method is simple, systematic and valid.
