In a wireless receiver the information being transmitted is either data or voice which is used to change a Radio Frequency (RF) carrier. In RF front end design the first stage is a LNA (Low Noise Amplifier). CMOS (Complementary Metal-Oxide-Semiconductor) has become a competitive technology for radio transceiver implementation of various wireless communication systems due to high cut off frequency, higher level of integrability, lower cost, etc. The main advantage of using CMOS for RF frontends is ease of integration with digital section leads to whole system on a single chip.
