Research on the Genetic Algorithms Applied to Evolvement Analog IC

摘要：

A module of genetic algorithms suitable for evolvement analog IC is designed,which dont relate with specific physical circuits and has excellent transplant ability. With the help of the interface module,the module adapted well to evolvement analog filter circuits and wide band high gain amplifier etc to optimize their performance. Using SMIC 0.18μm CMOS mixed technology,a evolvement AGC amplifier is designed and tapeouted successfully which has 30MHz operation frequency,40dB-70dB gain adjustment range. When output power is elevated maximal values,the AGC has -65dBm ldB compression point,-56dBm IP3. The circuits can be optimized using the core module of Genetic Algorithms or recover from failure. The results testing the chip and the module show that performance of AGC amplifier conforms to excellent features expected after about 40 generations.
