PROTOTYPE FRAMEWORK FOR KNOWLEDGE-BASED ANALOG CIRCUIT SYNTHESIS.

Abstract

An organization for a knowledge-based analog circuit synthesis tool is described. Analog circuit topologies are represented as a hierarchy of functional blocks; a planning mechanism is introduced to translate performance specifications between levels in this circuit hierarchy. A prototype implementation, the OASYS op-amp synthesis system, synthesizes sized transistor schematics for simple CMOS operational amplifiers from performance specifications and process parameters, and demonstrates the workability of the approach.
