Developing Automated Design Procedure for Operational Amplifier blocks

This paper deals with the development of automated design procedure (ADP) of analog building blocks dedicated for full-custom integrated circuit design of an operational amplifier (OpAmp). The design procedure proposed is divided into consecutive steps starting from the technology and model card choice followed by the selection of basic blocks for the OpAmp design. Subsequently, the established OpAmp architecture enters an advanced optimization aided by differential evolutionary algorithms. As a result, a robust set of circuit parameters attached to the OpAmp design is obtained, respecting the multi-criterion requirements for analog performance.
