Optimal Design of a 6.5 GHz Low Noise and High Gain CMOS Low Noise Amplifier By Single Objective Firefly Algorithm

A high-gain, low-power, highly linear cascode low noise amplifier (LNA) is considered with the circuit of an inductive source degeneration for employing at 6.5 GHz frequency; it is optimized by a capable swarm-based optimizer named firefly algorithm (FA) as an evolutionary method. By optimization of the noise figure (NF) and gain, the FA is useful while verifying all the design restrictions, e.g., the input and output matching, inverse isolation, linearity and power dissipation. Two situation studies have been accomplished for minimization of NF and maximization of gain. These two parameters optimization have been carried out by considering all parameters, for instance, a single objective function. The FA-based optimal consider paramet
