  • Wide-band low-noise CMOS amplifier
    Patent number: 8248161
    Abstract: A CMOS low-noise wide-band amplifier (LNA) 211 is provided. The LNA can include a Gm doubler 410, a source follower 420, and a coupling circuit (430/440) that couples a differential input to the Gm doubler with the source follower for achieving high linearity over a wide frequency range at a low supply voltage. The coupling circuit can capacitively couple (434/444) a differential input to a gate of the source follower. The gate can be biased to a supply voltage through variable resistors (436/446). A cross coupler (480) can be included in a push-pull buffer (450) for additional gain and for allowing the source follower to drive a low impedance load at low power.
