“…So, by nullor modeling we can turn the analysis of any active circuit to the analysis of its equivalent nullor circuit, which includes finding the circuit transfer functions. This is a significant achievement; for example, by nullor modeling of active circuits there is no need for two (I and V) graph representation of circuits, nor there is any requirement for 2-tree partitioning of circuit trees, typically used in the computation of cofactors to write the circuit transfer functions [11] [12] [13] [14]. Some examples may clarify the procedure.…”

The objective in this presentation is to introduce some of the unique properties and applications of nullors in active circuit analysis and designs. The emphasis is to discuss the role nullors can play in symbolic representation of transfer functions. To show this we adopt the topological platform for the circuit analysis and use a recently developed Admittance Method (AM) to achieve the Sum of Tree Products (STP), replacing the determinant and cofactors of the Nodal Admittance Matrix (NAM) of the circuit. To construct a transfer function, we start with a given active circuit and convert all its controlled sources and I/O-ports to nullors. Now, with a solid nullor circuit (passive elements and nullors) we first eliminate the passive elements through AM operations. This produces the STPs. Second, the all-nullor circuit is then used to find the signs or the STPs. Finally, the transfer function (in symbolic, if chosen) is obtained from the ratio between the STPs.
