Symbolic Analysis Using Floating Pathological Elements
The nullor-mirror pathological elements have been found useful in solving circuit analysis and design problems. They are further used to ideally represent various popular analog signal-processing properties that involve differential or multiple single-ended signals by utilizing the concept of floating mirror elements. For applying nodal analysis to the circuit containing such active devices with differential or multiple single-ended signals, we propose an efficient systematic analytical technique which directly performs symbolic analysis on the simpler RLC-nullor-floating mirror representations of circuits rather than their RLC-two-terminal pathological element-based counterparts. It releases the limitation of recently proposed symbolic analysis approaches and use simpler models which may be conductive to achieving high-performance symbolic nodal analysis. The feasibility and validity of the proposed method are demonstrated by practical circuit examples.
