A system for designing and optimizing integrated circuits. Design objectives and constraints are described as posynomial functions of the design parameters. The circuit design problem is then expressed as a special form of optimization problem called geometric programming, to which very efficient global optimization methods are applied. The present invention can thereby efficiently determine globally optimal circuit designs, or globally optimal trade-offs among competing performance measures such as, for example for an operational amplifier (op-amp), power, open-loop gain, and bandwidth. The present invention therefore yields automated synthesis of globally optimal circuit designs for a given circuit topology library, directly from specifications.
