Design automation system for analog circuits based on fuzzy logic

A design automation algorithm is proposed, and its effectiveness is evaluated by a prototype system. The goal is to obtain the near-optimum parameters for specifying the performance of the circuit. After the initial circuit parameters are calculated by a simple design technique, the performance is optimized. The system uses a circuit simulator to check the performance of the circuit. This performance is checked by using fuzzy logic. A production rule base is used for selecting a strategy to improve the performance. Using the prototype system, a differential amplifier was designed, with good results
