This Paper Describes our Challenge of Automatic Analog Circuit Design by Focusingon a Comparator Circuit which is One of the Important Analog Building Blocks. the Geneticalgorithm Chooses the Optimal Circuit Topology and HSPICE Optimizing Function Obtains Theiroptimal Parameter Values Automatically. Automatic Design for Analog Circuit has Not Beenrealized yet, even though Automatic Design is being Used in Digital Circuit Design; the Reasonbehind this is that the Number of Parameters to Be Considered in an Analog Circuit Designis much Larger than Digital Circuit Design. Nowadays it is Extremely Difficult to Design Icsmanually due to their Large Scale Integration and Hence their Automatic Design is Demanded. Wepresent our Automatic Circuit Design Owchart Programmed with Java Language which Realizes1-Click Automatic Synthesis of the Comparator, and Shows that our Method can Obtain a Betterperformance Comparator Compared to an Initially-Set Comparator.
