Abstract :
This paper describes changes of the minimum noise figure of a low noise amplifier designed based on a noise optimization technique. We show that the minimum noise figure of the LNA does not change with changes in Lg. To verify the effects a 1.575 GHz, 0.55 dB noise figure LNA was designed in CMOS 0.13 mum technology. Powered by a 1.1 V supply the LNA features 12.9 dB of gain and is stable over a wide frequency range. The. LNA draws only 1 mA and has an input return loss of -17 dB
