The CMOS LNA can be used for a single-chip CMOS RF receiver. The CMOS LNA can include a plurality of amplification stages coupled between an input terminal and an output terminal and a gain controller coupled to each of the plurality of amplifier stages, wherein the CMOS LNA does not include an inductor. Each of the amplification stages can have a symmetrically configured and sized first and second circuits to increase a dynamic range and a feedback loop.Field of SearchGain controlAutomatic Processor controlled Different gain stages Automatic gain control signal derived from information signal Plural stages controlled Semiconductor Local oscillator frequency control Reference oscillator or source Phase lock loop or frequency synthesizer Including differential amplifier Having gain control means Having D.C. feedback bias control for stabilization Having signal feedback means Including gain control means Including field effect transistor Having feedback means acting as variable impedance Including signal feedback means Including plural amplifier channels Having field effect transistor | |
