description Multi-output amplifiers with configurable source degeneration inductance and having good performance are disclosed. In an exemplary design, an apparatus (e.g., a wireless device or an integrated circuit) includes a gain transistor (534) and a configurable degeneration inductor (520) for an amplifier (500). The gain transistor (534) receives an input signal and provides an amplified signal. The amplifier (500) provides a single output signal in a first operating mode or a plurality of output signals in a second operating mode. The configurable degeneration inductor (520) is coupled to the gain transistor (534) and provides a first source degeneration inductance in the first operating mode or a second source degeneration inductance in the second operating mode. The second source degeneration inductance is less than the first source degeneration inductance and may be dependent on the number of output signals generated in the second operating mode.
