Abstract

The nullor as a network element is useful in the synthesis and analysis of active networks. It can be used to formulate the system of equations for symbolic nodal analysis. This brief presents a systematic analytical technique that performs efficient nodal analysis for RLC -nullor-mirror networks directly without replacing the mirror elements with their nullor equivalents. It is conducive to achieving high-performance symbolic nodal analysis since the RLC-nullor-mirror representation possesses reduced circuit complexity compared to the RLC-nullor equivalent. The feasibility and validity are demonstrated by two representative current-mode and voltage-mode circuits.
