Genetic-algorithm-based sythesis of low-noise amplifiers with automatic selection of active elements and DC biases

An advanced genetic-algorithm-based synthesis technique is proposed for design automation of microwave linear and low noise amplifiers. Jointly with automatic generation of amplifier schematics directly from performance requirements, it allows the selection of the best transistor types (sizes) and DC biases. As an example, the design of 2-10 GHz single-stage MMIC LNA is demonstrated.
