Abstract :
A 2.4 GHz CMOS Low Noise Amplifier (LNA) design is presented in this paper. A conventional cascode LNA structure is used with an inter-stage matching inductor. The two transistors of the cascode structure are considered as two individual stages. The off-chip inter-stage matching inductor is inserted between two stages. Using this method, overall gain can be increased and the noise figure of the LNA can be decreased
