SOURCE-SINK-NODE (SSN)-NETWORK TRANSFORMATION

A new network transformation, called the source-sink-node (SSN)-network transformation, is presented which transforms an arbitrary network into an equivalent active network containing only source and sink nodes (a so-called SSN-type network). The only active elements in the transformed network are inverting operational amplifiers. Although the transformation is very general, it is primarily useful for the analysis and design of switched-capacitor (SC) networks. Thus, for example, it permits the synthesis of stray-insensitive SC networks which are SSN-transformed versions of stray-sensitive SC networks. The transformation procedure is illustrated by some examples. © 1990 IEEE
