Abstract :
This paper presents a study on the contribution of the parasitic elements of the input integrated inductors to the noise figure of a fully integrated low noise amplifier (LNA). The LNA topology is a single-ended common source with inductive degeneration. The optimum trade-off between transistor noise and inductor series resistor noise is demonstrated. Good noise figure is obtained while maintaining sufficient gain and linearity. Simulated results concerning a 2.5 GHz LNA in a 0.25 μm partially depleted SOI-CMOS process, are presented to validate our analysis
