A low voltage/ low power 1.57 GHz low noise amplifier

This paper describes the design of a 1.57 GHz low noise amplifier. The LNA uses a modified cascode architecture and was implemented in CMOS 90 nm technology. Powered by a 1.0-V supply the LNA features 19 dB of gain and a 1.2 dBm noise figure. The LNA draws only 1.1 mA current and is stable over a wide frequency range. Input and output return losses of -5 dB and -15 dB have been achieved
