Fundamental limitations in precision analog circuits

The following principle of self compensation is formulated on the basis of an analysis of a general structure. The main technological inaccuracy of active elements' production influence the network characteristics. A sufficient condition of self compensation was found for ARC networks and its uniqueness was proved. In this case additional compensating circuit loops of feedback, put in networks, do not influence the set of device transfer functions and do not change the upper level of its dynamic range. For an amplifier, the second topological method is shown. It influences the realized transfer functions. With the help of the results we can formulate a new method of high-accuracy analog device building in an alternative submicron (less then micron) technology.
