In this paper, we present a methodology to synthesize CMOS RF devices from high-level circuit specifications into transistor netlists. The core of the methodology is an estimator of RF analog CMOS circuits, which evaluates the performance parameters of various circuit topologies. The estimation engine is based on a hierarchical analog performance estimator and a set of heuristics. The synthesis environment considers all performance parameters into account, and it relies on a genetic algorithm based heuristic method to search for a solution in a large design-space. The synthesis tool determines a solution set of design parameters such that the RF circuit satisfies the overall design constraints
