current conveyor (CCI), second generation current conveyor (CCII), third generation current
conveyor (CCIII), their inverting equivalents (ICCI (II)(III)), and/or their multiple output
topologies (MO (I) CCI (II)(III)). These nullor equivalents include only grounded resistors to
improve the formulation of equations in symbolic nodal analysis. In this manner, it is
highlighted the usefulness of the proposed models to calculate analytical expressions in MO …
