Analysis and Synthesis of Electronic Circuits by the Two-Graph Method

Pp. 147-172 (26)

Marian Pierzchała and Benedykt Rodanski


The general two-graph framework of a fully symbolic and semi-symbolic analysis environment for linear, time-invariant circuits is presented. A classical twograph approach for RLC-gm circuits as well as its extension for circuits containing nonadmittance elements is discussed. A brief introduction to approximate symbolic analysis, using the two-graph method, is included. In this chapter we also present a method of synthesis of active RC circuits on the basis of the two-graph method. The nullor approach is used to synthesize the RC network which has the voltage and the current graphs equivalent to the two-graph of the prototype LC network.
