  • Abstract
    This paper describes the effects of gate inductance on noise figure of a low noise amplifier designed based on a noise optimization technique. We show that the minimum noise figure of the LNA is not very sensitive to the changes in Lg. A 1.57 GHz, 0.55 dB noise figure LNA was designed in CMOS 0.13 μm technology to confirm the validity of the theory. 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.
