In this work, a continuous hybrid approach (CHA) to the determination of the FET model elements for the maximum transducer power gain in a frequency bond is presented. The CHA is based on a continuous parameter genetic algorithm and a controlled random search algorithm. The result obtained from the CHA are compared with the results obtained from the different types of genetic algorithm. The CHA gives better design than the others. (C) 2002 Wiley Periodicals, Inc.
