Abstract:
Gain control in complementary common gate and common source amplifiers is disclosed. In an exemplary embodiment, an apparatus includes a first amplifier stage configured to amplify an input signal at an input terminal to generate a first amplified signal. The first amplifier stage includes a current diverter that selectively diverts current to set a gain of the first amplifier stage. The apparatus also includes a second amplifier stage configured to amplify the input signal at the input terminal to generate a second amplified signal. The second amplifier stage includes a gain control circuit to set a gain of the second amplifier stage.
